Question

Simplify by using suitable identity.
(2x + 3) (2x - 5)​

Answer 1

Step-by-step explanation:

(x+a)(x-b) = x^2+ax-xb-ab

(2x+3)(2x-5) = 4x^2+6x-10x-15

= 4x^2-4x-15

Answer 2

Answer:

(2X+3) (2X-5)

${2x}^{2} - (b + a)x - ab$

${2x }^{2} - (5 + 3)x - 5 \times 3$

${2x}^{2} - (8)x - 15$

${2x}^{2} - 8x - 15$
