Question

1. Find the value of x by factorisation: 4x(2x+3)=36​

Answer 1

Answer:

The value of x is 3

Step-by-step explanation:

transposition method used

Answer 2

Answer:

x=3/2 or x=-3

Step-by-step explanation:

$8x^{2}$+12x=36

4($2x^{2}$+3x)=4*9

$2x^{2}$+3x-9=0

$2x^{2}$+6x-3x-9=0

2x(x+3)-3(x+3)=0

(2x-3)(x+3)=0

x=3/2 or x= -3
