Question

please solve this equation....​

Answer 1

so we should add p + q + r by puuting their value

RHS

( 7a2 +5ab - 8b2)+(4a2+ab+4b2)+(3a2-6ab+4b2)

no we will group the common

(-7a2+3a2+4a2)(5ab+ab-6ab)(-8b2+4b2+4b2)

(0)(0)(0)

so rhs is 0

and lhs is given

RHS = LHS

PROVED

bro see your question bcoz it is wrong it will be -7a2 then only answwr will come so i took -7a2
