Question

Give the values of a,b, and c after writing the equation in general form.
2/3(x-4)(x+5)=1

Answer 1

Answer:

a = 2, b = 2 and c = -43.

Step-by-step explanation:

2/3(x-4)(x+5)=1

Multiply through by 3

2(x - 4)(x + 5) = 3

2(x^2 + x - 20) = 3

2x^2 + 2x - 40 = 3

2x^2 + 2x - 43 = 0

So a = 2, b = 2 and c = -43.
