Question

If p =a ² - b² + 2ab, Q=a² + 4b² - 6ab, R = a²+ b² then p+Q-r​

Answer 1

Answer:

yes this answer is write P+Q-R

Answer 2

Step-by-step explanation:

the value of p=a2-b2+2ab

the value of q=a2+4b2-6ab

the value of r=a2+b2

Find the value of p+q-r

=a2-b2+2ab+a2+4b2-6ab-(a2+b2)

=a2-b2+2ab+a2+4b2-6ab-a2-b2

=a2+2b2-4ab

=(a-2b)2
