x^2 + 7x + 10

Since the 'x^2' term has a coefficient of '1' ( no number), then we look at the constant (10).

We need two numbers that multiply to '10' and add to '7'.

They are '5' & '2'

Hence setting up brackets

( x 5 )(x 2)

We note in the quadratic expression all the terms are positive(+) so plus(+) sign go in .

( x + 5)( x + 2)

Factored

Done!!!!
