Question

factorise - 3 x square - 144 X + 972 = 0​

Answer 1

Step-by-step explanation:

3x^2-144x+972

divide the equation by 3

x^2-48x+324=0

x^2-54x+6x+324=0

X(x-54)+6(x-54)=0

X=-6. or X=54

Answer 2

Step-by-step explanation:

- 3x² - 144x + 972 = 0

=> 3x² + 144 x - 972 = 0

=> 3x² + 162x - 18x - 972 = 0

=> 3x(x + 54) - 18(x + 54) = 0

=> (x + 54)(3x - 18) = 0

So,

Either | or

x + 54 = 0 | 3x - 18 = 0

=> x = - 54 | => 3x = 18

=> x = 6

Therefore, the required values of x are -54 or 6
