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.

Answer:

y = 8 · 10ˣ

Step-by-step explanation:

y = abˣ

When x = 0, y = 8.

8 = ab⁰

8 = a

When x = 3, y = 8000.

8000 = 8b³

1000 = b³

10 = b

The function is:

y = 8 · 10ˣ
