X⁴+5x²-6=0 solve for x
Snowcat [4.5K]
Let u = x², then we would have u² + 5u - 6 = 0

From here, we can factor it and get us (u-1)(u+6) = 0

So our solution for u is u = -6 or 1.

Now substitute u back to x².

x² = -6 or 1

x = ±√(-6) or ±√1

Since ±√(-6) is not real number, we ignore it.

Which leave us x = ±√1 = <span>±1

So our real solution is x = -1 or 1.</span>

There is a line that includes the point (1,10) and has a slope of 2. What is its equation in slope-intercept form?​
Dominik [7]

Answer:

y = 2x + 8

Step-by-step explanation:

You can input the slope and points into the point-slope equation and simplify:

y - 10 = 2(x - 1)

y - 10 = 2x - 2

y = 2x + 8
