Question

3x2-9x-30=0find the roots of the quadaratic equation by factorization method

Answer 1

Answer:

1st root =2 & 2nd root =(-5)

Step-by-step explanation:

3x²-9x-30=0,.

3(x²-3x-10)=0,

x²+3x-10=0/3,

x²+3x-10=0

As per factorisation method,

x²+5x-2x-10=0

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

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

x-2=0 l x+5=0

x=0+2 l x=0-5

x=2 l x=(-5)
