Question

Subtract 2x^2-6x-4

Answer 1

Answer:

The answer in descending powers of x:

• -2x²+2x+7

Step-by-step explanation:

We have to subtract $2x^2-6x-4$ from $4x^2-4x+3$

$4x^2-4x+3\:-\left(2x^2-6x-4\right)$

Distribute the Negative Sign

$=4x^2-4x+3+-1\left(2x^2-6x-4\right)$

$=4x^2+-4x+3+-1\left(2x^2\right)+-1\left(-6x\right)+\left(-1\right)\left(-4\right)$

$=4x^2+-4x+3+-2x^2+6x+4$

Combine Like Terms

$=4x^2+-4x+3+-2x^2+6x+4$

$=\left(4x^2+-2x^2\right)+\left(-4x+6x\right)+\left(3+4\right)$

$=2x^2+2x+7$

Thus, the answer in descending powers of x:

• -2x²+2x+7
