Question

What is the missing expression?

x8 + 3x5 = x5(_____)

anonymous · Answer

What you are doing here is simply factoring out the GCF. In this example that factor would be x^5. Once that is complete the missing expression would be x^(3)+3.

whats the answer

anonymous · Answer

try factoring the problem quickly removing $$x ^{5}$$ as your GCF. What do you have remaining?

anonymous · Answer

A key note here would be to remember that when dividing coefficients with exponents you subtract the exponents. For example $$x ^{8} \div x ^{5} = x ^{3}$$

anonymous · Answer

so the answer is x^3+3

anonymous · Answer
