Question

the roots of the equationx^2+7x+10=0 are​

Answer 1

Answer:

X²- 7X+10=0

X²-5X-2X+10=0

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

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

x-2= 0 x-5= 0

x= 2 x = 5

2and 5 are the roots

Answer 2

Answer:

x^2 + 7x + 10 = 0

x^2 + 5x + 2x + 10 = 0

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

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

hence , roots of the given equation :

• x + 5 = 0

x = -5

• x + 2 = 0

x = -2

-5 & -2 are the roots of the equation x^2 + 7x + 10 .
