Answer:
The simplified expression is
2x2+7x−13.
Step-by-step explanation:
Explanation:
Since this isn’t an equation, but rather an expression, it can only be simplified, not evaluated.
So let’s simplify it.
First distribute the
t (x2−1)
⇒3x2−3−(x2−7x+10)
Distribute the negative sign and drop the parentheses
:⇒3x2−3−x2+7x−10
Combine like terms:
⇒2x2+7x−13
