Question

Solve: 2x^3 + x^2 + 5x - 3 = 0
Step by step anyone? Much appreciated! :)

Answer 1

\[2^{3} + x^{2} +5x - 3 = 0\]
\[8 + x^{2} +5x - 3 = 0\]
\[5 + x^{2} +5x = 0\]
can you get X alone?

Answer 2

i think, there are no solution there

Answer 3

x = -1 or -5...?
>.>

Answer 4

it's a trinomial so it comes to be x(x + 5) = -5

Answer 5

if x=-1, ---> 2(-1)^3+(-1)^2+5(-1)-3=-2+1-5-3=-9 not equal zero
if x=-5, ---> 2(-5)^3+(-5)^2+5(-5)-3=-250+25-25-3=-253 not equal zero, so x=-1 or x=-5 is not solution

Answer 6

@.@... I'm so confused now....

Answer 7

it's a no solution
