Question

How many real solutions are there to the equation x2 − 7x + 12 = 0?

Answer 1

Hi there! 

We can find the answer by factoring the equation, then setting them up equal to zero.

x² - 7x + 12 = 0
(x - 3)(x - 4) = 0

x - 3 = 0                             x - 4 = 0
     x = 3                                   x = 4

So you have two real solutions for the equation x² - 7x + 12 = 0.

Hope this helped! :)
