Question

find the factorization.
x2+2x-80​

Answer 1

Answer:

Simplifying

X2 + 2x + -80 = 0

Reorder the terms:

-80 + X2 + 2x = 0

Solving

-80 + X2 + 2x = 0

Solving for variable 'X'.

Move all terms containing X to the left, all other terms to the right.

Add '80' to each side of the equation.

-80 + X2 + 80 + 2x = 0 + 80

Reorder the terms:

-80 + 80 + X2 + 2x = 0 + 80

Combine like terms: -80 + 80 = 0

0 + X2 + 2x = 0 + 80

X2 + 2x = 0 + 80

Combine like terms: 0 + 80 = 80

X2 + 2x = 80

Add '-2x' to each side of the equation.

X2 + 2x + -2x = 80 + -2x

Combine like terms: 2x + -2x = 0

X2 + 0 = 80 + -2x

X2 = 80 + -2x

Simplifying

X2 = 80 + -2x

Reorder the terms:

-80 + X2 + 2x = 80 + -2x + -80 + 2x

Reorder the terms:

-80 + X2 + 2x = 80 + -80 + -2x + 2x

Combine like terms: 80 + -80 = 0

-80 + X2 + 2x = 0 + -2x + 2x

-80 + X2 + 2x = -2x + 2x

Combine like terms: -2x + 2x = 0

-80 + X2 + 2x = 0
