How can the Binomial Theorem be useful in helping to prove and use polynomial identities

Step-by-step explanation:

Perhaps an actual question or example will help

Here is one case:

Prove that (2x -3y)^4 = <--- they would give that

LS = (2x - 3y)^4

= 1(2x)^4 + 4(2x)^3(-3y) + 6(2x)^2(-3y)^2 + 4(2x)(-3y)^3 + 1(-3y)^4

= 16x^4 - 96x^3 y + 216x^2 y^2 - 216x y^3 + 81y^4

= RS

make sure you are familiar with Pascal's triangle, it will be of great value to you

e.g. I took the values of 1 4 6 4 1 from the 5th row of the triangle

1

1 1

1 2 1

1 3 3 1

1 4 6 4 1

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5
