3p2 − 76 = –49
Write your answers as integers or as proper or improper fractions in simplest form.
p =
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.
