Question

10. Simplify the following algebraic expressions
a. (m2+5)(m2 - 4) - 18​

Answer 1

Answer:

$m^4+m^2-38$

Step-by-step explanation:

You can first write the equation as $(m^2+5)(m^2-4)-18$. By distributing the two parentheses, you get $(m^4-4m^2+5m^2-20)-18$. By combining like terms, you get $m^4+m^2-20-18$. By simplifying, you get $m^4+m^2-38$.
