Answer:
vertex = (- 3, 2 )
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
y = - 4(x + 3)² + 2 ← is in vertex form
with (h, k ) = (- 3, 2 )
Cross multiply
(3x - 1)(4x + 5) = (2x + 6)(6x - 4)
12x^2 + 11x - 5 = 12x^2 + 28x -24
Solve for x
-17x = -19
x = 19/17
