# How to solve $\sqrt{x+2}\geq x$?
How do you solve the inequality $$\sqrt{x+2}\geq{x}?$$
Now since $${x+2}$$ is under the radical sign, it must be greater than or equal to $${0}$$ to be defined.
So,
$${x+2}\geq{0}$$
Thus $${x}\geq{-2}$$
Now keeping this in mind, we can solve the inequality by squaring both the s... |

# How do you find the zeros for y=5x^2-2?
Mar 20, 2018
You set y equal 0, then solve the resulting equation for the value(s) of x.
#### Explanation:
Given: $y = 5 {x}^{2} - 2$
Set $y = 0$:
$0 = 5 {x}^{2} - 2$
Flip the equation:
$5 {x}^{2} - 2 = 0$
$5 {x}^{2} = 2$
Divide both sides by 5:
