How do I find the factor of the trinomial of y^2+7y-30
1 answer:
Find two numbers that multiply to -30 (last term) and add to 7 (middle coefficient)
The two numbers are 10 and -3
10 times -3 = -30
10 plus -3 = 7
Using those two values gets us the two factors (y+10) and (y-3)
Therefore, y^2+7y-30 factors to (y+10)(y-3)
The equation y^2+7y-30 = (y+10)(y-3) is true for all values of y.

I think the answer is A
Step-by-step explanation:
I'm not sure tho
1) f/3 + 22 = 17
2) f/3 + 22 - 22 = 17 - 22
= f/3 = -5
3) 3 • f/3 = 3(-5)
= f = 3(-5)
= f = -15
Your answer would be f = -15
