X^2+8x-55=10 what is the answer
Nataly [62]
Well...... I'm confused too but I'll go with:

<span>Simplifying
X</span>2<span> + 8x + -55 = 10

Reorder the terms:
-55 + X</span>2<span> + 8x = 10

Solving
-55 + X</span>2<span> + 8x = 10

Solving for variable 'X'.

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

Add '55' to each side of the equation.
-55 + X</span>2<span> + 55 + 8x = 10 + 55

Reorder the terms:
-55 + 55 + X</span>2<span> + 8x = 10 + 55

Combine like terms: -55 + 55 = 0
0 + X</span>2<span> + 8x = 10 + 55
</span>X2<span> + 8x = 10 + 55

Combine like terms: 10 + 55 = 65
X</span>2<span> + 8x = 65

Add '-8x' to each side of the equation.
X</span>2<span> + 8x + -8x = 65 + -8x

Combine like terms: 8x + -8x = 0
X</span>2<span> + 0 = 65 + -8x
X</span>2<span> = 65 + -8x

Simplifying
X</span>2<span> = 65 + -8x

Reorder the terms:
-65 + X</span>2<span> + 8x = 65 + -8x + -65 + 8x

Reorder the terms:
-65 + X</span>2<span> + 8x = 65 + -65 + -8x + 8x

Combine like terms: 65 + -65 = 0
-65 + X</span>2<span> + 8x = 0 + -8x + 8x
-65 + X</span>2<span> + 8x = -8x + 8x

Combine like terms: -8x + 8</span><span>x = 0
-65 + X</span>2<span> + 8x = 0
