Factor:j) x(x+2) + y (x + 2) - 5(x + 2)k) 5y2 - 10y3l) ax + ay + az

Sagot :

Given:

[tex]x\left(x+2\right)+y(x+2)-5\left(x+2\right)[/tex]

Required:

We need to factorize the given expressions.

Explanation:

[tex]x\left(x+2\right)+y(x+2)-5\left(x+2\right)[/tex]

The common multiple in all terms is (x+2).

Take out the common term (x+2).

[tex]x\left(x+2\right)+y(x+2)-5\lparen x+2)=(x+2)(x+y-5)[/tex]

Final answer:

[tex]\begin{equation*} (x+2)(x+y-5) \end{equation*}[/tex]

K)

Given:

[tex]5y^2-10y^3[/tex]

Explanation:

The given expression can be written as follows.

[tex]5y^2-10y^3=5y^2-5\times2\times y^2\times y[/tex]

[tex]5y^2-10y^3=5y^2-5y^2\times2y[/tex][tex]\text{ The common multiple in all terms is }5y^2.[/tex][tex]\text{ Take out the common term }5y^2.[/tex]

[tex]5y^2-10y^3=5y^2(1-2y)[/tex]

Final answer:

[tex]5y^2(1-2y)[/tex]

l)

Given:

[tex]ax+ay+az[/tex]

Explanation:

[tex]\text{ The common multiple in all terms is }a.[/tex]

[tex]\text{ Take out the common term }a.[/tex]

[tex]ax+ay+az=a(x+y+z)[/tex]

Final answer:

[tex]a(x+y+z)[/tex]
