Question

Find the roots of the equation
x²+7x+10=0
​

Answer 1

Step-by-step explanation:

${x}^{2} + 7x + 10 = 0 \\ {x}^{2} + 5x + 2x + 10 = 0 \\ x(x + 5) + 2(x + 5) = 0 \\ (x + 5)(x + 2) \\ \\ x = - 5 \\ x = - 2$

I hope it helps you

Answer 2

Answer:

x²+7x+10=0

x²+2x+5x+10=0

(x²+2x)+(5x+10)=0

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

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

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

x=(-2) and x=(-5)

Therefore, the roots of the equation are (-2) and (-5).
