Question

If P = a^2 – b^2 + 2ab
Q = a^2 + 4b^2 – 6ab
R = b^2 + b
S = a^2 – 4ab
T = -2a^2 + b^2 –ab + a


Find P + Q + R + S – T.

please tell

Answer 1

Answer:

given,P+Q+R+S-T

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

=(a-b)²+{(a+b)+(a-b)}-6ab(Continue on like this)

Step-by-step explanation:

i think question is little different.
