Resolve in factors. I) x⁴+x²+1

masha68 [24]

Answer:

let a = x² (a ≥ 0), we have the equation:

a² + a + 1 = 0

⇔ a² + 2.1/2.a + 1/4 + 3/4 = 0

⇔ (a + 1/2)² = -3/4 (unreasonable)

=> no solutions

Solve for x. 25 - 3x = -5(1 - x) - 2x

grandymaker [24]

Answer:

$x = 5$

Step-by-step explanation:

25 - 3x = -5(1 - x) - 2x

We have to first get rid of the parenthesis:

$-5 * 1$ ==> -5

$-5 * -x$ ==> 5x

So now you should have:

25 - 3x = -5 + 5x - 2x

Combine like terms:

25 - 3x = -5 + 5x - 2x

25 - 3x = -5 + 3x

Add 3x to both sides:

25 - 3x = -5 + 3x

+ 3x = + 3x

And you should have:

25 = -5 + 6x

Add 5 to both sides:

25 = -5 + 6x

+5 = +5

30 = 6x

Divide 6 to both sides:

$\frac{30}{6}$ = $\frac{6x}{6}$

5 = x

Please help!!!!!!!!!!!!

Point-slope form is y - y1 = m (x + x1)

First you need to find m [slope] by subtract y2 and y1 and divide it by the outcome of x2 - x1

13 - (-9) = 22
-2 - 9 = -11
22/-11 = -2

Plug in the first point (as instructed) into the equation.

y - (-9) = -2 (x - 9)

Simplify the beginning.

y + [9] = [-2] (x + [-9])

(The brackets are the fill in the blanks)
