Question

the roots of the equation X square + 7 x + 10 =0 a ) 2 and 5 b) -2 and 5 c) -2 and -5 d) 2 and -5​

Answer 1

Answer:

x² + 7x + 10=0

x² + 5x + 2x + 10 = 0

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

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

either x+5=0

then x=-5

or x+2=0

then x=-2

Answer 2

Answer:

C)-2 and -5.

Step-by-step explanation:

x^2+7x+10

x^2+5x+2x+10

x(x+5)+2(x+5)

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

x+5=0; x+2=0

x= -5; x= -2
