multiply using FOIL and identify values of a, b, & c.
(5x +5)(6x - 8)

• algebra -

30x^2-10x-10

And what do you mean about the values of a,b,and c

That's just the way the question was asked?

• algebra -

30 x^2 -10 x - 40

a = 30
b = -10
c = -40

Thanks!

I assume it means a, b and c in quadratic formula

if
a x^2 + b x + c = 0

then
x = [ -b +/- sqrt (b^2-4ac) ] / 2a

Which I used to factor the expression in your question Lea.
