2 answers:
Answer:
Step-by-step explanation:
2x² - 13x + 20
Sum = -13
Product = 40
Factors= (-8) ; (-5)
2x² - 13x + 20 = 2x² - 8x - 5x + (-5)*(-4)
= 2x(x - 4) -5(x - 4)
= (x - 4)(2x - 5)
Answer:
(2x - 5)(x-4)

Find K and M
Make K the subject in:
Substitute in
![\frac{1}{5} * [3 * ( M - 24) - 24] = \frac{1}{3} * M](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7D%20%2A%20%5B3%20%2A%20%28%20M%20-%2024%29%20-%2024%5D%20%3D%20%5Cfrac%7B1%7D%7B3%7D%20%2A%20M)
Open brackets
![\frac{1}{5} * [3M - 72 - 24] = \frac{1}{3} * M](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7D%20%2A%20%5B3M%20-%2072%20-%2024%5D%20%3D%20%5Cfrac%7B1%7D%7B3%7D%20%2A%20M)
![\frac{1}{5} * [3M -96] = \frac{1}{3} * M](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7D%20%2A%20%5B3M%20-96%5D%20%3D%20%5Cfrac%7B1%7D%7B3%7D%20%2A%20M)
Multiply both sides by 15
![3* [3M -96] = 5 * M](https://tex.z-dn.net/?f=3%2A%20%5B3M%20-96%5D%20%3D%205%20%2A%20M)
Collect like terms
Divide both sides by 4
Substitute in
