Recognizing the Vertex and Discriminant
Consider the quadratic function f(x) = 2x2 – 8x – 10.

The x-component of the vertex is .

The y-component of the vertex is .

The discriminant is b2 – 4ac = (–8)2 – (4)(2)(–10) = .

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

36

step-by-step explanation:

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
