X³ - 12x² + 35x
x(x² - 12x + 35)
x(x-5)(x-7)
Usually I would use my head, but you can use whatever you want.
Question 1. 7:11
Question 2. 27 units of K
How to solve the questions-
1. 14/22 divide the numerator and the denominator by 2. This would give you 7/11
2. If the ratio is 12/9 and the amount of N is 36, you’re basically multiplying 12 *3, so then you have to multiply 9 *3=27.
