Question

Which expression is equivalent to (7h^2-7h+5)-(10h^2-3h+6)?
1. -3h²-4h-1
2. -3h²-10h+11
3. 17h²-4h-1
4. 17h²-10h+11

Answer 1

Answer:

$-3h^{2} -4h-1$

Step-by-step explanation:

Remove the  parentheses and rewrite the expression as

$7h^{2} -7h+5-10h^{2}+3h-6$

Then we combine like terms

$(7h^{2} -10h^{2} )+(-7h+3h)+(5-6)$

Simplify

$-3h^{2} -4h-1$
