Question

Factorize by splitting the middle term :-
3x² + 19x - 14​

Answer 1

Step-by-step explanation:

Product = -42

Sum = 19

Numbers are 21 & -2

we can split the middle term by

$3x {}^{2} + 21x - 2x - 14$

3x (x + 7) - 2 (x+ 7) = 0

(3x - 2)(x+7) = 0

x = 2/3, x = -7

Answer 2

Step-by-step explanation:

3x² + 19x - 14

= 3x² + 21x - 2x - 14

= 3x( x + 7 ) - 2( x + 7 )

= ( x + 7 )(3x - 2).
