Question

What is the solution of the equation?
36x^2 = 100


-9/25 , 9/25
-3/5 , 3/5
-25/9 , 25/9
-5/3 , 5/3

Answer 1

36x^2=100

x^2=25/9

Can you solve the rest?

Answer 2

Remember a square root has a positive and negative answer.

Answer 3

x^2 = 100/36 (divide by 36 on both sides)
x^2 = 25/9 (reduce fraction)
x = sqrt(25/9) (square root both sides)
x = 5/3 (simplify. the sqrt of 25 = 5 and the sqrt of 9 = 3)

Answer 4

Don't just type the answer next time :P .

Answer 5

@QuantumTorch :

A square root is positive and negative. So it's -5/3 AND 5/3

Answer 6

thank yall sooo much .

Answer 7

Welcome :) .

Answer 8

I didn't put both +/- because they were already in the answers, so I figured that was assumed. :P

Answer 9

36x^2 = 100
x^2 = 100/36
x = +/- (10/6)
