Question

multiply the polynomial (a+5)3
the product is?

Answer 1

\[(a+5)^{3}\]

Answer 2

you want cube of a+5. if yes then simply apply formula on it.

Answer 3

a+125 ?/idk im confused with this

Answer 4

@uri this square formula not cube. @Avon yes you can calculate but you have to multiply one more time with a+5

Answer 5

@uri im lost like what

Answer 6

A+625 @gsRttN

Answer 7

uri formula is right , after applying that formula again multiply the answer with a+5

Answer 8

a+625 is ans ? i don't know answer i am not calculating it , i am just giving you solution , apply formula and try to calculate it own

Answer 9

@gsRttN i dont even see @uri formla anymore

Answer 10

#formula

Answer 11

(a+b)^3 = a^3 + b^3 + 3ab(a+b) this is formula . try to apply it on your equation.

Answer 12

\[a ^{4}+625\] @gsRttN

Answer 13

a^4+625 is answer? @Avon

Answer 14

@Avon you get it?

Answer 15

no @gsRttN \[a ^{3}+15a ^{2}+75a+125 is the final answer\]

Answer 16

Answer 22

this is exactly same as last one. just replace 5 by 3. and you will get your answer

Answer 23

Use this identity!
\[(x+y)^3 = x^3 + y^3 + 3x^2y + 3xy^2\]
Now solve for
\[(a+3)^3 = a^3 + 3^3 + 3a^2.3 + 3.3^2.a\]
Understood? :)

Answer 24

thanks @ivettef365

Answer 25

yw :)

Answer 26

avon gave you the correct answer...
a^3 + 15a^2 + 75a + 125

Answer 27

thanks everyone for the help i appreciate it

Answer 28

@Avon don't ever try to solve equation using any online calculator . try to solve it by hand. it will help you other wise it become habit and you will fail to solve such simple equation. so always try by own hand. Best of luck

Answer 29

i will try @gsRttN
