35 POINTS, WILL GIVE BRAINLIEST, PLS HURRY !! (:
How do you factor trinomials? How can we check the binomial factors to verify
that they are truly factors? Use
y=x2+7x-18 as your example.

Answer 1

Answer:

Step-by-step explanation:

y=x2+7x-18

y = (x-2)(x+9)

     (x-2)(x+9 ) = 0    shows the zeroes to be 2 and -9

  you can show they are truly factors by substituting the roots into the original equation to see that it = 0
