Answer:
3x² + 13x + 4
Step-by-step explanation:
3x³ - 2x² - 61x - 20
3x³ - 15x² + 13x² - 65x + 4x - 20
[3x²(x - 5) + 13x(x - 5) + 4(x - 5)]/(x-5)
3x² + 13x + 4
Y = -2x² + 8x - 18
x = -b/2a
x = -8/2(-2)
x = -8/-4
x = 2
y = -2x² + 8x - 18
y = -2(2)² + 8(2) - 18
y = -2(4) + 16 - 18
y = -8 - 2
y = -10
(x, y) = (2, -10)
Vertex: (2, -10)
Axis of Symmetry: x = 2

There are two circles with center A and D. The tangent line touches both point B and C. The given measurements are enough to solve for the missing value and the solution is shown below:
AB=9
BC=26
DC=8
Solve for the measurement of AC which the hypotenuse of legs AB and BC by Pythagorean theorem:
c²=a²+b²
c²=9²+26²
c=AC=27.51
Solve for angle of A
sin A=26/27.51
A=70.93°
Finally, we solve for the length of AD using SOH
sin 70.93°=AD/27.51
AD=26
The answer is 26.
