Starting with 4f^2 - 49 = 0:
Add 49 to both sides to get:
4f^2 = 49
Divide both sides by 4:
f^2 = 49/4
Take the square root of both sides (remembering to include both positive and negative solutions):
f = ±7/2
So the solutions for f are f = 7/2 or f = -7/2.
Solve for f.
4f2–49=0
Write each solution as an integer, proper fraction, or improper fraction in simplest form. If there are multiple solutions, separate them with commas.
