Answer:
Sketch the following three graphs:
1) y = (x - 5)²
2) y = -(x - 5)²
3) y = x - 5
First two are parabolas with vertex at (5,0)
Third one is a line which intersects both the parabolas as (5,0)

if you solve those equations for "c" and "d" respectively, you'd get, well the Q point of c,d
4x^2+28x+49
4x^2+14x+14x+49
2x(2x)+2x(7)+7(2x)+7(7)
2x(2x+7)+7(2x+7)
(2x+7)(2x+7)
(2x+7)^2
The missing term is 28.
Answer:
x = 12
Step-by-step explanation:
Step 1: Write quadratic
x² - 24x + 144 = 0
Step 2: Factor
(x - 12)(x - 12) = 0
Step 3: Find roots
x - 12 = 0
x = 12
