Question

3x²-x-4
pleas --------------------

Answer 1

$\huge\mathcal{\purple{A}}{\mathcal{\green{N}}}{\mathtt{\pink{S}}}{\mathcal{\blue{W}}}{\mathcal{\purple{E}}}{\mathcal{\green{R}}}{\pink{!}}{\blue{!}}$

3x² - x - 4

= 3x² + 3x - 4x - 4

= 3x(x+1) -4(x+1)

= (x+1)(3x-4)

Answer 2

Answer:

x=-1 (or) x=4/3

Step-by-step explanation:

3x^2-x-4=0

3x^2-4x+3x-4=0

x(3x-4)+1(3x-4)=0

(x+1)(3x-4)=0

x=-1 (or) x=4/3
