What are the values of a, b, and c in the quadratic equation 0 = 5x – 4x2 – 2?

a = 5, b = 4, c = 2
a = 5, b = –4, c = –2
a = –4, b = 5, c = –2
a = 4, b = –5, c = –2

a = –4, b = 5, c = –2

Step-by-step explanation:

We can re-write the quadratic equation 0 = 5x – 4x2 – 2 like this:

– 4x2 + 5x – 2 = 0

ax2   + bx  + c = 0

then

a = -4

b = 5

c = -2

hihi so drawing these 2 triangles is fairly simple. all that's left is finding the height of each one. luckily, we have a side length and an angle, so there is a trig function we can use to solve for the height. the easiest one to use would be tangent, since we have 2/3 things needed to find and the third needed is what we are solving for. tan(73°) * 30 ~= 98.13 and tan(73°) * 35 ~= 114.45
