3p2 − 76 = –49

Question

Write your answers as integers or as proper or improper fractions in simplest form.

p =

Answer 1

To solve for p, we can start by isolating p on one side of the equation.

Adding 76 to both sides of the equation, we get:

3p2 = -49 + 76

3p2 = 27

Next, we divide both sides of the equation by 3:

p2 = 27/3

p2 = 9

Taking the square root of both sides, we get:

p = ±√9

Simplifying the square root, we have:

p = ±3

Therefore, the value of p is 3 or -3.
