If 2x²+6x-4=0, how do you factor it and what is x?
jeka57 [31]
          2x² + 6x - 4 = 0
2(x²) + 2(3x) - 2(2) = 0
        <u>2(x² + 3x - 2)</u> = <u>0</u>
                 2              2
           x² + 3x - 2 = 0
                          x = <u>-(3) +/- √((3)² - 4(1)(-2))</u>
                                                2(1)
                          x = <u>-3 +/- √(9 + 8)</u>
                                           2
                          x = <u>-3 +/- √(17)
</u>                                         2<u>
</u>                          x = -1.5 <u>+</u> 0.5√(17)
                          x = -1.5 + 0.5√(17)    U    x = -1.5 - 0.5√(17)
