Question

factorise 3 x square - 2 x minus 8​

Answer 1

Answer:

$3 x { }^{2} - 2x - 8 \\ \ \\ 3x {}^{2} - 6x + 4x - 8 \\ 3x(x - 2) + 4(x - 2) \\ x = 2$

Hence, the value of x is 2

Answer 2

Answer:

hey there

Step-by-step explanation:

3x^2-2x-8

we will factorise it by using middle term split

that means we will take any to factors of 8 which either by subtraction or by addition result in the middle term that is 2

so

3x^2-(4-2)x-8

3x^2-4x+2x-8

3x(x-4)+2(x-4)

(3x+2)(x-4)

there you go

hope it helps
