Question

2x ² + x - 6=0 by factorisation method​

Answer 1

Answer:

2x²+x−6=0

2x²+4x−3x−6=0

2x(x+2)−3(x+2)=0

(2x−3)(x+2)=0

x=3/2;−2

Answer 2

2x^2 + x - 6 = 0

Sum = 1

Product= -12

So ,

=> 2x^2 -3x + 4x - 12 = 0

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

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

=> x = -2 or x = 3 / 2
