Question

expand(2a+b+5) ² using identity

​

Answer 1

_________________________

We need to expand (2a+3b+5)²

Comparing the given expression with (x+y+z)²p,

we find that x=2a,y=3b and z=5

Therefore, using Identity V, we have

(2a+3b+5)²

=(2a)²+(3b)²+(5)² +2(2a)(3b)+2(3b)(5)+2(5)(2a)

=4a²+9b²+25+12ab+30b+20a
