Answer 1

Answer:

Hello Mate❤❤❤

(2x+1)³

Solution:-

=>8x³+12x²+6x+1

step by step explanation:-

We use Pascal's triangle for cofficient

=>(a+b)² ____1

__________1,2,1

=>(a+b)³___1,3,3,1

So, we need 1,3,3,1

the power of the term will sum to 3.

And the starting first then will be 3 and descend in 1s.

=>(2x+1)³ =>1(2x)³+3(2x)²(2)+3(2x)(1)+1×1³

=>(2x+1)³=>8x³+12x²+6x+1

Have a NYC day
