To find the zeros you can factor the problem, graph the function, or plug in an answer and see if the result is 0. If given answers I usually plug and chug.
The answer is D
(-5)^2 - 9(-5) - 70
25 + 45 - 70 = 0 this is a root. or a zero of the function
Answer:

Answer:
I wish I was able to answer for you, but I dont know this stuff yet
Answer:
x^2-x-90=0 x^2-10x+9x-90 x(x-10)+9(x-10)
(x+9)(x-10)=0
Solutions are 0-9=-9 and 0+10=10.
10-9=1= a+b
