Using the quadratic formula, which of the following are the zeros of the quadratic equation below?
y = x2 - X-5
A. x = 11/19
O B. x149
O C. x-lt
2
o D. x=-11/21
O

y=x2-X-5 is zero of quadratic equation

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1

answer: it is 1: 47 pm
