Example 8: Multiply
(i) (x-4) and (2x + 3)​

Answer 1

Step-by-step explanation:

Example 8: Multiply

(i) (x-4) and (2x + 3)=x *2x+3)-4(2x+3)

x×2x+x×3-4x×2x-4×3

2x2 +3x-8x-12

2x2 -5x-12

Answer 2

Answer:

4 OR -3/2

Step-by-step explanation:

( x - 4 ) ( 2x + 3 )

2x^2 + 3x - 8x - 12

2x^2 - 8x + 3x - 12

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

( x - 4 ) ( 2x + 3 )

x = 4 OR 2x = -3

x = -3/2
