Question

Solve the equation using the quadratic formula.

x2 + 3x -2 = 0

Question 7 options:

x = −2±29√4

x = 3±11√2

x =−2±17√3

x = −3±17√2

Answer 1

the last one is the answer

Answer 2

`x=(-3\pm√(17))/(2)`

Explanation:

We have been given an equation
`x^2+3x-2=0`. We are asked to solve the given equation.

To solve our given equation, we will use quadratic formula.

`x=(-b\pm√(b^2-4ac))/(2a)`

Substitute the values:

`x=(-3\pm√(3^2-4(1)(-2)))/(2(1))`

`x=(-3\pm√(9+8))/(2)`

`x=(-3\pm√(17))/(2)`

Therefore, option D is the correct choice.
