I tried to think of a fancy formula for it, then decided it's just easier to list them:

1
2
3
11
12
13
21
22
23

That's 9 of them.

$\\ \rm\longmapsto 2^{4x+4}=64^{x+2}$

$\\ \rm\longmapsto 2^{4x+4}=(2^6)^{x+2}$

$\\ \rm\longmapsto 2^{4x+4}=2^{6(x+2)}$

$\\ \rm\longmapsto 4x+4=6(x+2)$

$\\ \rm\longmapsto 4x+4=6x+12$

$\\ \rm\longmapsto 4-12=6x-4x$

$\\ \rm\longmapsto -8=2x$

$\\ \rm\longmapsto x=\dfrac{-8}{2}$

$\\ \rm\longmapsto x=-4$

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.
