Question

x^2 - 3x - 2 ≈ 0 ( solve the following using formula 2x^2 + 13x +15 ≈ 0 )

Answer 1

hay!!

Dear friend -

(I) x²-3x-2=0

=> x²-2x-1x-2

=> x(x-2) +1(x-2)

=> (x+1) (x-2)

(II)

2x²+13x+15=0

=> 2x²+10x+3x+15=0

=> 2x(x+5)+3(x+5)

=> (2x+3) (x+5)

I hope it's help you

Answer 2

hay!!


1.

x²-3x-2=0

x²-2x-1x-2

x(x-2) +1(x-2)

(x+1) (x-2)

2.

2x²+13x+15=0

2x²+10x+3x+15=0

2x(x+5)+3(x+5)

(2x+3) (x+5)
