Question

1.Find the x intercepts of y=3(x-5)(x+2)
2.Find the roots of y=x^2-5x-14

Answer 1

To find x-intercepts set y to 0 and solve for x.

Answer 2

To find the roots set y to 0 and solve for x.

Answer 3

are their any answer choices?

Answer 4

to solve the second equation factor the left side of

x^2 - 5x - 14 = 0

this can be factored to give (x + a)(x + b)

to find a and b you need 2 numbers whose product is -14 and whose sum is -5

Answer 5

i already finished the 1st one i got x=-2 and x=5
but not the 2nd

Answer 6

as I said you need to factor the second equation first

Answer 7

ok thx i got it now

Answer 8

you correct for the first one.
