Given the numerical equation:
(10p – 4q^2 – q) – (q^2 – 7p + 9p^2)
Simplify.
Solution:
In order to simplify the equation, we first start by distributing the minus sign to each value inside the parentehesis. If similar signs are introduced, multiplied or divided to one another, the answer will become positive, hence if the signs are opposite to one another, then the answer will become negative. In our case we have a negative sign, and a negative sign therefore the resulting sign will be positive.
= (10p – 4q^2 – q) – (q^2 – 7p + 9p^2)
= 10p – 4q^2 – q – q^2 + 7p - 9p^2
Combine like terms.
= 17p - 5q^2 - 9p^2 - q
Final answer:
= 17p - 5q^2 - 9p^2 - q
