Question

i need help with factoring. i have about 10 factoring questions like these:

[srry i don't know how to type the squared sign on here so instead i'll use ^)

1. (q+2)^=25

2. y^+6y+9=49

if anyone could explain how to get the answer, it would be amazingly helpful. thanks sooo much :]

Answer 1

(q+2)²=25     given

(q+2)(q+2)=25     expand

q²+2q+2q+4=25     foil

q²+4q+4=25     addition prop

q²+4q-21=0     subtraction prop

(q+7)(q-3)=0     factor

q=-7 or q=3

y²+6y+9=49

y²+6y-40=0

(y+10)(y-4)=0

y=-10 or y=4

Answer 2

well i'm going to email u the answers using word so it will be easier to show...
