Question

How many, and what type of, solutions does y=5x^2−10x−12 have? 2 rational solutions 1 rational solution 2 irrational solutions 2 nonreal solutions

Answer 1

2 irrational solutions

Explanation:

y = 5x² - 10x - 12

B² - 4AC

(-10)² - 4(5)(-12)

100 + 240

340 > 0

So two distinct real roots.

Since sqrt(340) is not rational, the roots are also irrational

Answer 2

Answer:2 nonreal solutions
