Answer 1

Step-by-step explanation:

(i) (2x + 3)(2x – 4) (2x) (2x – 4) + 3 (2x – 4) = (2x) (2x – 4) + 3 (2x – 4) = (2x × 2x) – 4 (2x) + 3(2x) – 3 (4) = 4x2 – 8x + 6x – 12 = 4x2 + (- 8 + 6)x – 12 = 4x2 – 2x – 12Read more on Sarthaks.com - https://www.sarthaks.com/981917/find-the-product-of-i-2x-3-2x-4

Answer 2

Answer:

4x^2 + 2x - 12

Step-by-step explanation:

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

Formula : -

( a + b ) ( a + c ) = a^2 + ( b + c )a + bc

Here,

a = 3x

b = 4

c = - 3

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

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

= 4x^2 + ( 4 - 3 ) 2x + ( - 12 )

= 4x^2 + ( 1 ) 2x - 12

= 4x^2 + 2x - 12
