Question

factories 3x²-3x-18​

Answer 1

Answer:

3x^2 - 9x + 6x - 18

3x(x - 3) + 6 (x - 3)

(3x + 6) (x - 3)

Answer 2

The factorisation of 3$x^2$ - 3x - 18​ is equal to (x - 3)(3x + 6).

Step-by-step explanation:

We have,

3$x^2$ - 3x - 18​

To find, the factorisation of 3$x^2$ - 3x - 18​ = ?

∴ 3$x^2$ - 3x - 18​

By Factorisation Method,

= 3$x^2$ - 9x + 6x - 18​

= 3x(x - 3) + 6(x - 3)

= (x - 3)(3x + 6)

∴ The factorisation of 3$x^2$ - 3x - 18​ = (x - 3)(3x + 6)

Thus, the factorisation of 3$x^2$ - 3x - 18​ is equal to (x - 3)(3x + 6).
