Solution for =4x^2+3x+x^2-2x equation:


Simplifying
0 = 4x2 + 3x + x2 + -2x

Reorder the terms:
0 = 3x + -2x + 4x2 + x2

Combine like terms: 3x + -2x = 1x
0 = 1x + 4x2 + x2

Combine like terms: 4x2 + x2 = 5x2
0 = 1x + 5x2

Solving
0 = 1x + 5x2

Solving for variable 'x'.
Remove the zero:
-1x + -5x2 = 1x + 5x2 + -1x + -5x2

Reorder the terms:
-1x + -5x2 = 1x + -1x + 5x2 + -5x2

Combine like terms: 1x + -1x = 0
-1x + -5x2 = 0 + 5x2 + -5x2
-1x + -5x2 = 5x2 + -5x2

Combine like terms: 5x2 + -5x2 = 0
-1x + -5x2 = 0

Factor out the Greatest Common Factor (GCF), '-1x'.
-1x(1 + 5x) = 0

Ignore the factor -1.

Subproblem 1

Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0

Subproblem 2

Set the factor '(1 + 5x)' equal to zero and attempt to solve: Simplifying 1 + 5x = 0 Solving 1 + 5x = 0 Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + 5x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + 5x = 0 + -1 5x = 0 + -1 Combine like terms: 0 + -1 = -1 5x = -1 Divide each side by '5'. x = -0.2 Simplifying x = -0.2

Solution

x = {0, -0.2}
