Question

find the roots of the equation x ×2 + 7 x + 10 = 0
​

Answer 1

Answer:

X^2 - 7X + 10 = 0

Here we use factorisation method

X^2 - 5X - 2X + 10 = 0

X ( X - 5 ) - 2 ( X - 5 ) = 0

( X - 5 ) ( X - 2 ) = 0

Now ,

X - 5 = 0

X = 5

and,

X - 2 = 0

X = 2

Hence the roots of this equation are 5 and 2

Answer 2

$\huge\boxed{Answer}$

= x²+7x+10=0

= x²+5x+2x+10=0

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

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

= x=−5,−2
