Review: to simplify an expression, combine like terms by adding orsubtracting coefficients only. like terms have the same variable (letter orsymbol that represents a quantity).example: 17a + 4 - 5a - 3 = (17a - 5a) + (4-3) = 12a + 1simplify this expression. 10b + 7 - 3 - 2

10b + 2

Step-by-step explanation:

To simplify this expression. 10b + 7 - 3 - 2​ use the sample you demonstrated above to simplify it

10b + 7 -3 -2

combine the like terms

10b + 7 - 5

10b + 2

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i
