Question

find the root of x²+3x-10=0​

Answer 1

Answer:

The equation x

2

−3x−10=0 can be solved as

x

2

−5x+2x−10=0

⇒x(x−5)+2(x−5)=0

⇒(x+2)(x−5)=0

⇒x=−2 and x=5

Answer 2

Answer:

You can answer this question by the method splitting the middle term

x²+3x-10=0

x²-2x+5x-10=0

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

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

x= -5 and x=2

So, the roots are -5 and 2.
