1.	10. Simplify the following algebraic expressionsa. (m2+5)(m2 - 4) - 18
Answer» 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 $m^4+m^2-38$ .
