Which of the following is the standard form of the equation 5x2 - 20x = 15? x2 - 4x = 3 x2 - 4x - 3 = 0 5x2 - 20x - 15 = 0

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.

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
