Question

$3x2 - 2x - 8$
​

Answer 1

$\huge\underline\mathbb\orange{Answer:-}$

Step-by-step explanation:

3x^2-2x-8

3X^2-6x+4x-8

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

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

1. X= -4/3

2. X = 2

Answer. 2

Answer 2

✦ Question :-

↠ 3x² - 2x - 8

$\Large{\underline{{\bf{Solution:-}}}}$

By using middle term splitting method :-

↠3x² - ( 6 - 4 ) x - 8

↠ 3x² - 6x + 4x - 8

↠ 3x ( x - 2 ) 4 ( x - 2 )

↠ ( 3x + 4 ) ( x - 2 )

Extra Information :-

Factorization of Quadratic polynomials of the form x² + bx + c.

• In order to factorize x² + bx + c we have to find numbers p and q such that p + q = b and pq = c.
• After finding p and q, we split the middle term in the quadratic as px + qx and get desired factors by grouping the terms.
