Answer:

Value of a = 8

Value of b = 2

Value of c = - 10

Step-by-step explanation:

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

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

=  > 8 {x}^{2}  - 10x + 12x - 15

=  > 8 {x}^{2}  + 2x - 10

As per the general form of a quadratic eqn. a {x}^{2}  + bx + c

Value of a = 8

Value of b = 2

Value of c = - 10

9

out of

√

18

. You should have:

√

√

2

But since

√
