Answer:

Step-by-step explanation:

1. y = x^{2}  - 2x- 15 = x^{2}  - 5x +3x -15 = x(x-5) + 3(x-5) = (x-5)(x+3)

2.

4x^{2}  - 8x - 12 = 0\\x^{2} - 2x - 3 = 0\\x^{2} - 3x + x - 3 = 0\\ x(x-3) + 1 (x-3) = 0\\(x-3)(x+1) = 0

x= 3 and x = -1

3. x^{2}  - 36 = 0

  (x-6) (x+6) = 0

x = 6 and -6

tankabanditka [31]

His monthly income if he earns an equal amount every month is Rs 3,613.33

<h3>How to determine the monthly income?</h3>

The annual income is given as:

Annual income = Rs 43,360
