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

That's just the way the question was asked?

30 x^2 -10 x - 40

a = 30

b = -10

c = -40

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.
