Question

Solve 3x2 + 4x = 2 with the quadratic equation!. I got -2-+ sqr of 40/3 but I don't see it in the answer choices. help?

Answer 1

The quadratic equation is described as:

`x=\frac{-b+- \sqrt{ b^(2)-4ac } }{2a}`

where a is the coefficient of x2, b is the coefficient of x and c is the constant.

Substituting and solving for x would result to:

`x=\frac{-4+- \sqrt{ 4^(2)-4*3*-2 } }{2*3}`

`x1=(-4+ 2√(10) )/(6)`

`x2=(-4- 2√(10) )/(6)`
