Question

Find the zeros by factoring.

1) l(x)=x^2+7x+10

Answer 1

you need getting two numbers with sum equal 7 and product equal 10 - ok,?

Answer 2

let being a and b so than you can rewriting this quadratic (x+a)(x+b)

so than i give you the a you will can give the b ?

Answer 3

so a=2 than you know that 2+b=7 and 2*b=10 - so what will be b=?

Answer 4

will it be 5?

Answer 5

yes right so you know that a=2 and b=5 so how will be factored this quadratic ?

Answer 6

how i have wrote above

(x+a)(x+b) = x^2 +7x +10 --- ok. ?

Answer 7

hope these was helpfully - bye

Answer 8

yes, it was very helpful.
Thank you
