Question

(2x+3)(4x-7) , you get a new expression of the form ax^2+bx+c what is value of a , b , and c

Answer 1

(2x+3)(4x-7)

To convert this quadratic formula on the general expression, we need to multiply both parenthesis as follows:

8x^2 - 14x + 12x - 21 =

8x^2 -2x - 21

where a, b and c correspond to the coefficients of the equation:

a = 8

b = -2

c = -21
