Question

Solve. 2x2 + 16x + 50 = 0
Answer

Answer 1

This one use quadratic formula.
a=2, b=16, c=50
(-16 + or - sqrt(16^2 - 4(2)(50)))/(2*2)

Answer 2

(-16 + or - sqrt(-656))/(4)

Answer 3

(-16 + or - 4sqrt(-41))/(4) then factor out 4
4(-4 + or - sqrt(-41))/(4) and then
x = -4 + sqrt(-41)
x = -4 - sqrt(-41)

Answer 4

16^2 - 4(2)(50) = 256 - 400 = -144

So you should have

(-16 + or - sqrt(-144))/(4)

Answer 5

damn I did -(16^2) for some reason Jim is right^

Answer 6

everything else is right though, so good job

Answer 7

well I mean everything before it of course

Answer 8
