Answer:
Step-by-step explanation:
Quadratic Polynomial = (x+3)(x-4) = x^2 - x - 12
x = -3
x^2 - x - 12 = 9 - (-3) - 12 = 0
x = 4
x^2 - x - 12 = 16 - 4 - 12 = 0
thus -3 and 4 are zeroes of x^2 - x - 12
next
Mean – Mode = 3 (Mean – Median)
Mean - 29 = 3 (Mean - 26)
Mean - 29 = 3Mean - 78
78 - 29 = 2Mean
49 = 2Mean
Mean = 24.5
