Sagot :

Answer:

-6

Step-by-step explanation:

So, this problem wants you to multiply 5x+1 with 2x-3 and place it in ax^2 + bx + c form and add a. b, and c all together.

So, let's start by multiplying the expressions together

( 5x + 1 )( 2x - 3 ) = 5x ( 2x - 3 ) + 1(2x - 3)

                           = 10x^2 - 15x + 2x -3

                           = 10x^2 - 13x -3

There, we have our answer of 10x^2 - 13x - 3

So, a = 10, b = -13, and c = -3

a + b + c = 10 -13 - 3

              = -6
