8 - 3x + 12 = 2x
(Distribute the -3 to the quantity in the parentheses)
20 = 5x
(Simplify by adding like terms)
4 = x
(Divide both side by 5 to isolate the variable)
X = 4

Answer:
Discriminant = 93, two real roots/solutions
Step-by-step explanation:
Discriminant = b² - 4ac = (9)² - 4(3)(-1) = 81 + 12 = 93
Since 93>0, the quadratic equation has two real roots/solutions.
