Question

Subtract the following expression: 4x+5x^2-8 from 4x^3-5x+5​

Answer 1

Step-by-step explanation:

Simplifying

4x + 3 = 5x + 5

Reorder the terms:

3 + 4x = 5x + 5

Reorder the terms:

3 + 4x = 5 + 5x

Solving

3 + 4x = 5 + 5x

Solving for variable 'x'.

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

Add '-5x' to each side of the equation.

3 + 4x + -5x = 5 + 5x + -5x

Combine like terms: 4x + -5x = -1x

3 + -1x = 5 + 5x + -5x

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

3 + -1x = 5 + 0

3 + -1x = 5

Add '-3' to each side of the equation.

3 + -3 + -1x = 5 + -3

Combine like terms: 3 + -3 = 0

0 + -1x = 5 + -3

-1x = 5 + -3

Combine like terms: 5 + -3 = 2

-1x = 2

Divide each side by '-1'.

x = -2

Simplifying

x = -2
