Answer:

Step-by-step explanation:

Zeros α = -3 and β = -4

Quadratic equation: x² - (α + β)x + αβ = 0

x² - (-3-4)x + (-3)*(-4) = 0

x² - (-7)x + 12 =0

x² + 7x + 12 = 0

Answer:

(3, 1)

Step-by-step explanation:

Let the coordinates of B be (x, y)

Since, M is the midpoint of AB.

Therefore, by mid point formula:

$1 = \frac{ - 1 + x}{2}, \: \: \: 3 = \frac{5 + y}{2} \\ \\ 2 = - 1 + x, \: \: \: 6 = 5 + y \\ \\ 2 + 1 = x, \: \: \: 6 - 5 = y \\ \\ 3 = x, \: \: \: 1 = y \\ \\ x = 3, \: \: \: y = 1 \\ \\ B = (3, \: \: 1)$
