Question

Solve the inequality y^2-3y greater than 18 sorry couldn't find the greater than sign

Answer 1

The greater than sign (on my computer) is above the period key. So, just jit SHIFT then type the period key.

So, I guess you want to solve y^2 -3y > 18

We can factor that as y * (y -3) > 18

Well, if it is

y^2 -3y -18 = 0 then

Then y = 6 and y = -3

Hope that helps

Explanation:

Answer 2

y > 6 or y < -3

Explanation:

y² - 3y > 18

Complete the square.

y² - 3y + 9/4 > 18 + 9/4

y² - 3y + 9/4 > 81/4

(y - 3/2)² > 81/4

y - 3/2 > 9/2, or y - 3/2 < -9/2

y > 6 or y < -3
