Question

Factorize : (i) 2x^2 + 9x + 10 (ii) 3x^2 – 4x – 4

Answer 1

Answer:

I) x= -2 Or x=-5/2

ii) x=2 or x=-2/3

Step-by-step explanation:

i) 2x²+9x+10=0

2x²+4x+5x+10=0

2x(x+2)+5(x+2)=0

(x+2)(2x+5)=0

x+2=0 or 2x+5=0

x= -2 Or x=-5/2

ii) 3x²-4x-4=0

3x²-6x+2x-4=0

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

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

x-2=0 or 3x+2=0

x=2 or x=-2/3
