Question

Factorize 15x [] +3x^2-18​

Answer 1

Step-by-step explanation:

by middle term splitting

3x²+15x-18 =0

dividing both side by 3

x²+5x-6=0

x²+6x-x-6=0

x(x+6)-1(x+6)=0

(x-1)(x+6)=0

x=-6,1

I m not sure about the answer so u can recheck it.

Answer 2

Answer:

(x+2)(3x-9).

Step-by-step explanation:

your questions: 15x + 3x^2 -18.

solution:- 3*18=54

and if we multiply 6 by 9 so we get 54.

and add them then we get 15.

So, equation become:-

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

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

now take common......

3x(x+2) - 9(x+2)

(x+2)(3x-9) ans...
