Question

Reduce -8 + b2 by 5 + b2. -3 2b² - 3 -13

Answer 1

Answer:

After making the subtract the answer is -13.

Step-by-step explanation:

In this case the question is a subtract, we just have to subtract both of the equations, this is:

$-8+b^{2} -(5+b^{2} )\\=-8+b^{2} -5-b^{2} \\=-13$

After making the subtract the answer is -13.

Answer 2

-8+b2-(5+b2). Since the - is outside the paranthesis the signs inside change: -8+b2-5-b2. -8-5=-3, b2-b2=0. Your answer: -3 :)
