Factoring by grouping x^2 + 4y + 2x + 2xy pls explain with work too!!!

Gennadij [26K]

${x}^{2} + 4y + 2x + 2xy$

We can factorise this expression by grouping. First let us arrange it in this way

$= {x}^{2} + 2xy + 2x + 4y$

Let us bracket them like this:

$= ( {x}^{2} + 2xy) + (2x+ 4y)$

In the first bracket portion, take x as common and in the second expression, take 2 as common.

$= x(x + 2y) + 2(x + 2y) \\ = (x + 2)(x + 2y)$

Answer:

$(x + 2)(x + 2y)$

Hope you could understand.

If you have any query, feel free to ask.

I’m the triangle shown below what is the approximate value of x

Dafna1 [17]

Answer:

The answer is choice B: 22.52 units.

Step-by-step explanation:

We use the Pythagoras's theorem which says for a right triangle with sides $x,y$ and hypotenuse $z$ :

$x^2+y^2=z^2.$

In our case

$z=26$

$y=13$

So we solve for $x:$

$x=\sqrt{z^2-y^2}=\sqrt{26^2-13^2} =\boxed{22.52\: units.}$

Which is choice B.
