x² + 7x + 10 = 0

or, x² + 5x + 2x + 10 = 0

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

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

=> (x+5)=0 |or| (x+2)=0

or, x = (-5) or, x = (-2)

Answer:

x^2-7x+10=0

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

x=5 and x=2                                              

Explanation:

When adding, -7 has to be the sum and when multiplying, +10 has to be the answer.

-5 and -2 are the only ones who fit this criteria.

(-5)+(-2)=(-5-2)= -7

(-5)x(-2)=10
