Simplifying
5(x + 2) * 2(x + -2) = 7(x2 + -4)
Reorder the terms:
5(2 + x) * 2(x + -2) = 7(x2 + -4)
Reorder the terms:
5(2 + x) * 2(-2 + x) = 7(x2 + -4)
Reorder the terms for easier multiplication:
5 * 2(2 + x)(-2 + x) = 7(x2 + -4)
Multiply 5 * 2
10(2 + x)(-2 + x) = 7(x2 + -4)
Multiply (2 + x) * (-2 + x)
10(2(-2 + x) + x(-2 + x)) = 7(x2 + -4)
10((-2 * 2 + x * 2) + x(-2 + x)) = 7(x2 + -4)
10((-4 + 2x) + x(-2 + x)) = 7(x2 + -4)
10(-4 + 2x + (-2 * x + x * x)) = 7(x2 + -4)
10(-4 + 2x + (-2x + x2)) = 7(x2 + -4)
Combine like terms: 2x + -2x = 0
10(-4 + 0 + x2) = 7(x2 + -4)
10(-4 + x2) = 7(x2 + -4)
(-4 * 10 + x2 * 10) = 7(x2 + -4)
(-40 + 10x2) = 7(x2 + -4)
Reorder the terms:
-40 + 10x2 = 7(-4 + x2)
-40 + 10x2 = (-4 * 7 + x2 * 7)
-40 + 10x2 = (-28 + 7x2)
Solving
-40 + 10x2 = -28 + 7x2
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-7x2' to each side of the equation.
-40 + 10x2 + -7x2 = -28 + 7x2 + -7x2
Combine like terms: 10x2 + -7x2 = 3x2
-40 + 3x2 = -28 + 7x2 + -7x2
Combine like terms: 7x2 + -7x2 = 0
-40 + 3x2 = -28 + 0
-40 + 3x2 = -28
Add '40' to each side of the equation.
-40 + 40 + 3x2 = -28 + 40
Combine like terms: -40 + 40 = 0
0 + 3x2 = -28 + 40
3x2 = -28 + 40
Combine like terms: -28 + 40 = 12
3x2 = 12
Divide each side by '3'.
x2 = 4
Simplifying
x2 = 4
Take the square root of each side:
