Question

can someone help me with expansion and give me like practise problems plssss????

Answer 1

You mean multiplication of algebraic expressions?

Answer 2

no exspansion of algebraic epression

Answer 3

Try these perhaps :P
1.\[ 3x^2 y^4 (2x-3y+4z)\]
2. \[3\sqrt{x} (x^4 -x^2y^5)\]

Answer 4

@Callisto that's too difficult for him, give him something easier...

\[\Large x(3x^2+4)=\]

\[\Large x^5(3x^2-2x)=\]

then try callisto's one ! ;)

Answer 5

or these...
1. 2(x+y)
2. 12 ( x^2 + xy^2 - x^3)

Answer 6

@Kreshnik my new ones are easier now :)

Answer 7

@Callisto I agree ! ;)

Answer 8

First, explain a little for you..
2(x+y) = 2(x) + 2(y) = 2x+2y
Can you try the 2nd question of my 2nd post?

Answer 9

\[\Large x^2(2x+4)=2x\cdot x^2+4\cdot x^2\]

\[\Large x^4(2x^2-7x)=x^4\cdot 2x^2-x^4\cdot 7x=2x^{4+2}-7x^{4+1}=2x^6-7x^5\]

Exampless...

Answer 10

\[\Large 2x\cdot x^2+4x^2=?\]

and you also are supposed to know these rules ! :

\[\LARGE x^a\cdot x^b=x^{a+b}\]

\[\LARGE \frac{x^a}{x^b}=x^{a-b}\]

\[\LARGE x^{-a}=\frac{1}{x^a} \quad \quad and \quad \quad \frac{1}{x^a}=x^{-a}\]

\[\LARGE \sqrt[b]{x^a}=\left(x\right)^{\frac ab}\]
