Question

factorise the following 3 y square - 4 Y - 4​

Answer 1

Answer:

$3 {y}^{2} - 4y - 4 \\ \\ 3 {y}^{2} - 6y + 2y - 4 \\ \\ 3y(y - 2) + 2(y - 2) \\ \\( 3y + 2)(y - 2) \\ \\ take \: 3y + 2 = 0 \: and \: y - 2 = 0 \\ \\ 3y = - 2 \: \: and \: y = 2 \\ \\ y = \frac{ - 2}{3} and y=2\\ hence \: the \: value \: of \: y = \frac{ - 2}{3} and \: 2$

Answer 2

Answer:

the answer is (y=2),(y=2/3)

Step-by-step explanation:

now lets factorize the following equation,

here 'y' is changed as 'x'

                   $3x^{2} -4x-4\\</p><p>                    3x^{2} +2x-6x-4\\</p><p>                    x(3x+2)-2(3x+2)\\</p><p>                    (3x+2) (x-2)\\</p><p>                     x = 2/3\\</p><p>                      x = 2$
