Question

factorise 3 x square - 4z - 4

Answer 1

$3 {x}^{2} - 4x - 4 \\ 3 {x}^{2} - 6x + 2x - 4 \\ 3x(x - 2) + 2(x - 2) \\ (3x + 2)(x - 2) \\ x = - 2 \div 3 \: or \: 2$
HOPE THIS HELP YOU :)

Answer 2

I hope your question is :

3x² - 4x - 4

Answer :

3x² - 4x - 4

Sum = -4 ,Product = -4

So numbers are -6 & 2

= 3x² - 6x + 2x - 4

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

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