Question

i will mark as brainliest 3. Divide after factorising the first polynomial.
2x+ 4x - 12 by x - 2
2 -114-63 by -9
3x2 + 4x-7 by 3x +7 please answer​

Answer 1

Answer:

1. (X+6)

2.(2X-7)

3.(X-1)

Step-by-step explanation:

first multiply co-efficient of $x^{2}$ and last term .. then find its factor in such a way that after subtracting or adding these two factors we get middle term

like here we multiply (1) * (12) = 12  and its factor a=6 and b=2 and a-b=4 which is our middle term co-efficient.

$x^{2}$ + 6x - 2x - 12x

taking x common from $x^{2}$ and 6x , and -2 common from 2x and 12x we get,

x(x + 6) -2(x + 6)

it becomes

(X+6)(X-2)

now divide it by (X-2) we get,

(X+6)
