Question

(iv) 3.x2-x-4
$3x {}^{2} - x - 4$
​

Answer 1

$\huge\color{lime}\boxed{\colorbox{black}{⭐Answer :-⭐}}$

$3 {x}^{2} - x - 4 \\ 3 \times 4 = 12$

DO THE FACTORS OF 12.

we get ,

12 = 2×2×3

since 4-3=1 and 4×3=12 .

then ,

$3 {x}^{2} - 4x + 3x - 4 \\ x(3x - 4) - 1(3x - 4) \\ (x - 1)(3x - 4)$
