Question

if A=a²+2ab+b²and B=-2a²-7ab-6b²find the value of A+B.​

Answer 1

A+B= a2+2ab+b2+(-2a2-7ab-6b2)

=3a2-5ab-5b2.......

.................tnx

Answer 2

${a}^{2} + 2ab + {b}^{2} + ( - {2a}^{2} - 7ab - 6 {b}^{2} )$

${a}^{2} + 2ab + {b}^{2} - {2a}^{2} - 7ab - {6b}^{2}$

${ ( - a)}^{2} - 5ab - {5b}^{2}$

${a}^{2} - 5ab - 5 {b}^{2}$
