━━━━━━━☆☆━━━━━━━

▹ Answer

1/3a + c - 7b

▹ Step-by-Step Explanation

(4/3a - 3c - 5b) + (-a - 2b + 4c)

Remove the parentheses

(4/3a - 3c - 5b) + (-a - 2b + 4c)

Rewrite

4/3a - 3c - 5b - a - 2b + 4c

Calculate

1/3a - 3c - 5b - 2b + 4c

Final Answer

1/3a + c - 7b

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.
