Question

Q-5 Simplify combining like terms. c) a2 + b2+ c 2 - ( 2 a 2 + 2 b2-5 c2) d) p-(p-q)-q(9-p)​

Answer 1

Given:

Two Equation are given to us which are

[tex]a)a^2+b^2+c^2-(2a^2+2b^2-5c^2)\\ b)p-(p-q)-q(9-q)[/tex]

To Find:

Simplify the equation ?

Step-by-step explanation:

• a) we have given equation to simplify the equation we will take like terms all together then solve according to BODMAS rule

               [tex]a)a^2+b^2+c^2-(2a^2+2b^2-5c^2)\\ =a^2+b^2+c^2-2a^2-2b^2+5c^2)\\ =a^2-2a^2+b^2-2b^2+c^2+5c^2\\ =-a^2-b^2+6c^2[/tex]

• b) we have given equation to simplify the equation we will take like terms all together then solve according to BODMAS rule

                [tex]b)p-(p-q)-q(9-q)\\\\ =p-p+q-9q+q^2\\\\ =q^2-8q[/tex]

Thus we get simplified form of part a  and b.
