Question

Find the roots of the equation x^2+7x+10=0​

Answer 1

Answer:

x^2 +7x +10 =0

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

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

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

x+2 =0 & x+5 =0

=>=>=> x = -2 , -5 <=<=<=

Answer 2

${\huge{\underline{\boxed{\red{\mathcal{Answer}}}}}}$

Given:

• x^2 + 7x + 10 = 0

To Find:

• Roots of the equation.

Solution:

$\implies x^2 + 7x + 10 = 0 \\\implies x^2 + 5x + 2x + 10 = 0 \\\implies x(x + 5) + 2(x + 5) = 0 \\\implies (x + 2)*(x + 5) = 0 \\\bf{\implies x = -2\:\: OR\:\: x = -5}$

Hope it helps!
