Answer:

x(x + 1)(x² - x + 1)

Step-by-step explanation:

Given

$x^{4}$ + x ← factor out x from each term

= x(x³ + 1) ← x³ + 1 is a sum of cubes and factors as

= x(x + 1)(x² - x + 1) ← in factored form

Answer:

x(x^3 + 1)

Step-by-step explanation:

x^4 + x

We got the common factor x so, we got:

x(x^3 + 1)

This is the simpliest form it can get

Hope it helped :3

Axis of Symmetry: x = 2

Step-by-step explanation:

You can look at the labeling from my last answer, the parabola is just upside down but it is still the same label.

Hope it makes sense :)

Answer:

For the time interval 0 to 2 the ball is in the air.

Select the options according to this.

Step-by-step explanation:

The equation should be $h(t)=-16t^{2} -30t+124$

Let's find the x intercepts to answer this question.

To find x intercept where the h(t) is 0.

$-16t^{2} -30t+124=0$

Solve the equation for t.

Use quadratic formula to solve the equation.

a=-16

b=-30

c=124

$x=\frac{-b+/- \sqrt{b^{2}-4ac } }{2a}$

Plug in the values of a, b and c into the formula

$x=\frac{30+/-\sqrt{(-30)^{2}-4(-16)(124) } }{2(-16)}$

Simplify it

$x=\frac{30+/- \sqrt{900+7936} }{-32}$

$x=\frac{30+/-\sqrt{8836} }{-32}$

$x=\frac{30+/-94}{-32}$

Simplify it to get two values for x

$x=\frac{30+94}{-32} =-3.875\\\\x=\frac{30-94}{-32} =2$

x can not be negative, here x represents time t.

So, it starts from 0 and remains in the air for 2 seconds.
