Prime factors are 5, 5, 7, 7. Factors are any combination of the above, i.e. 5 x 5 = 25 5 x 7 = 35 7 x 7 = 49 5 x 5 x 7 = 175 5 x 7 x 7 = 245
The prime factors of 525 are: 3 x 5 x 5 x 7
2 x 3 x 7 x 25 2 x 5 x 7 x 15 5 x 5 x 6 x 7 3 x 5 x 5 x 14 3 x 5 x 7 x 10 2 x 5 x 5 x 21 2 x 3 x 5 x 35
5 x 7 x 7 = 245
5/7=x/63Cross-multiply.5*63=x*7Divide by 7, isolating the x:5*63/7=xSimplify.5*63/7=5*9=45x=45
(x + 7)2 = 5 x + 7 = ±√5 x + 7 - 7 = -7 ± √5 x = -7 ± √5
