Answer:
- (2x+3)^2=
- (a+b)^2
- =>a^2+2ab+b^2
- =>a into or axa+2xaxb+bxb or b into b
- =>a=2x,b=3
- =>2x into 2x +2 into 2x into 3+3 into 3
- =>4x^2 or 4x into x+12x+9
- =>4x^2+12x+9
- Note:-where ever above 'into' is written ,there you are instructed to consider that as multiplication and '^' this sign shows 'raised to the power' and when any numerical value is written just for example 2, that means square of the written number and the expression is done on the basis of the formulae (a+b)x(a+b) or (a+b)^2.
