Question

Find the roots of the quadratic equation by factorisation
2xsquare+5 X-12=0.​

Answer 1

Answer:

$x=\frac{3}{2}$ or $x=-4$

Step-by-step explanation:

Quadratic equation $2x^2+5x-12=0$ is factored into : $(2x-3)(x+4)=0$

• $2x-3=0$ or $x+4=0$

∴ $x=\frac{3}{2}$ or $x=-4$

Answer 2

Answer:

2x2 + 5x -12 =0

2x2 -8x -3x -12 =0

2x (×-4) +3 (x - 4)

(2x+3) (x-4)
