<h3>ꫝꫀꪗ</h3><h2><u>✍</u><u> </u><u>Answer:</u><u>-</u></h2>

(x + 5)(x + 2)

Use the algebraic identity,

(x + a)(x + b) \\  =  {x}^{2}  + (a + b)x + ab

Now,

a = 5

b = 2

Substitute the values of a & b in the identity & solve the equation.

{x}^{2}  +( a + b)x + ab \\   = x {}^{2}  + (5 + 2)x + 5 \times 2 \\   = {x}^{2}  + 7x + 10

✎ \: (x + 5)(x + 2) =  {x}^{2}  + 7x + 10
