(10x+11)(10x+13)
identity -(x+a)(x+b)=x^+(a+b)x+ab
putting a=11 b=13
=10x^+(11+13)x+11*13
=10^+24x+143
identity -(x+a)(x+b)=x^+(a+b)x+ab
putting a=11 b=13
=10x^+(11+13)x+11*13
=10^+24x+143

We can solve it by using the identity ( x + a ) ( x+ b ) = (x)(x) + ( a+ b)x + ab
The answer would be like this-
(10x)(10x) + (11+ 13)10x + 143
100xx + 240x + 143
