Answer 1

$(2x - 5)(x + 3) = 2 {x}^{2} + x + a \\ 2 {x}^{2} + 6x - 5x - 15 = 2x { }^{2} + x + a \\ 2 {x}^{2} - 2 {x}^{2} + x - x - 15 = a \\ - 15 = a \\ a = - 15$

Answer 2

$\huge\underline\mathfrak\purple{❥︎ANSWER}$

-15

Step-by-step explanation:

(2 {x} - 5)(x + 3)(2x−5)(x+3)

2x( x + 3) - 5(x + 3))2x(x+3)−5(x+3))

2 {x}^{2} + 6x - 5x - 152x

2

+6x−5x−15

2 {x + x - 15}2x+x−15

a= -15

hope it helps you...☺☺
