Solution for 0=50(x^2+2x-20) equation:


Simplifying
0 = 50(x2 + 2x + -20)

Reorder the terms:
0 = 50(-20 + 2x + x2)
0 = (-20 * 50 + 2x * 50 + x2 * 50)
0 = (-1000 + 100x + 50x2)

Solving
0 = -1000 + 100x + 50x2

Solving for variable 'x'.

Combine like terms: 0 + 1000 = 1000
1000 + -100x + -50x2 = -1000 + 100x + 50x2 + 1000 + -100x + -50x2

Reorder the terms:
1000 + -100x + -50x2 = -1000 + 1000 + 100x + -100x + 50x2 + -50x2

Combine like terms: -1000 + 1000 = 0
1000 + -100x + -50x2 = 0 + 100x + -100x + 50x2 + -50x2
1000 + -100x + -50x2 = 100x + -100x + 50x2 + -50x2

Combine like terms: 100x + -100x = 0
1000 + -100x + -50x2 = 0 + 50x2 + -50x2
1000 + -100x + -50x2 = 50x2 + -50x2

Combine like terms: 50x2 + -50x2 = 0
1000 + -100x + -50x2 = 0

Factor out the Greatest Common Factor (GCF), '50'.
50(20 + -2x + -1x2) = 0

Ignore the factor 50.

Subproblem 1

Set the factor '(20 + -2x + -1x2)' equal to zero and attempt to solve: Simplifying 20 + -2x + -1x2 = 0 Solving 20 + -2x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -20 + 2x + x2 = 0 Move the constant term to the right: Add '20' to each side of the equation. -20 + 2x + 20 + x2 = 0 + 20 Reorder the terms: -20 + 20 + 2x + x2 = 0 + 20 Combine like terms: -20 + 20 = 0 0 + 2x + x2 = 0 + 20 2x + x2 = 0 + 20 Combine like terms: 0 + 20 = 20 2x + x2 = 20 The x term is 2x. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2x + 1 + x2 = 20 + 1 Reorder the terms: 1 + 2x + x2 = 20 + 1 Combine like terms: 20 + 1 = 21 1 + 2x + x2 = 21 Factor a perfect square on the left side: (x + 1)(x + 1) = 21 Calculate the square root of the right side: 4.582575695 Break this problem into two subproblems by setting (x + 1) equal to 4.582575695 and -4.582575695.

Subproblem 1

x + 1 = 4.582575695 Simplifying x + 1 = 4.582575695 Reorder the terms: 1 + x = 4.582575695 Solving 1 + x = 4.582575695 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = 4.582575695 + -1 Combine like terms: 1 + -1 = 0 0 + x = 4.582575695 + -1 x = 4.582575695 + -1 Combine like terms: 4.582575695 + -1 = 3.582575695 x = 3.582575695 Simplifying x = 3.582575695

Subproblem 2

x + 1 = -4.582575695 Simplifying x + 1 = -4.582575695 Reorder the terms: 1 + x = -4.582575695 Solving 1 + x = -4.582575695 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = -4.582575695 + -1 Combine like terms: 1 + -1 = 0 0 + x = -4.582575695 + -1 x = -4.582575695 + -1 Combine like terms: -4.582575695 + -1 = -5.582575695 x = -5.582575695 Simplifying x = -5.582575695
