Solve –2x2 – 16x – 44 = 0
answer please using quadtratic equation ...?
1 answer:
The quadratic formula is one way to obtain the solution of the quadratic<span> equation. It is expressed as:
x = (-b +/- </span>√b² - 4ac ) / 2a
where, for this problem, a = -2, b = -16 and c = -44.
We solve as follows:
x = (-b +/- √b² - 4ac ) / 2a
x = (-(-16) +/- √(-16)² - 4(-2)(-44) ) / 2(-2)
x = (16 +/- √256 - 352 ) / -4
x = (16 +/- √-96 ) / -4
x = -(16 +/- 4i√6 ) / 4

Step-by-step explanation:
Let c = hypotenuse and a = leg 1 and b = leg 2. If c² > a² + b², then it is obtuse. If it is less, then it is acute. I hope it helps.
