Question

Y=x^2+7x+10

What are the x-intercepts of the graph of the equation above?
A.(2,0)and(-5,0)
B.(2,0)and(5,0)
C.(-2,0)and(-5,0)
D.(-2,0)and(5,0)

Answer 1

C is correct. Do you understand these?

Answer 2

Sort of. It is kind of confusing. Can you explain it?

Answer 3

take y = 0 to get x-intercepts
in other words x^2+7x+10=0
solve for x

Answer 4

factor out will giving us
(x+2)(x+5)=0
for zeroes take each fator equal 0
x+2=0 ----> x = -2
x+5=0 ----> x = -5

Answer 5

*factor

Answer 6

so, the x-intercepts are (-2,0) and (-5,0)

Answer 7

@RadEn Thank you sooo much! That really helped
