Answer:
Option B, x² - 4x - 3 = 0
Step-by-step explanation:
The equation is 5x² - 20x = 15
The most simplified form of an equation is called the standard form of an equation.
So we have to simplify the given equation to convert it into standard from.
5x² - 20x = 15
5 (x² - 4x) = 15
x² - 4x = 3
x² - 4x - 3 = 0
Option B is the answer.
