Question

This equation will be in standard form if you subtract from both sides and add to both sides.

5x^2+3x-8=2x^2-7x

True or False

Answer 1

True
You need to subtract 2x^2 from both sides and add 7x to both sides. This leaves:
3x^2 + 10x -8 = 0

Answer 2

Answer:

Answer is True.

Step-by-step explanation:

Given expression is $5x^2+3x-8=2x^2-7x$

Here, Standard form is in which all terms are on LHS and terms should be in decreasing order of degree.

Consider,

$5x^2+3x-8=2x^2-7x$

Add both sides by 7x, we get

$5x^2+3x-8+7x=2x^2-7x+7x$

$5x^2+10x-8=2x^2$

Subtract 2x² from both sides, we get

$5x^2+10x-8-2x^2=2x^2-2x^2$

$3x^2+10x-8=0$

Therefore, Answer is True.
