Which equation has the same solution as 2x^2+x-3=0

Sagot :

ax² + bx + c = 0
2x² + x - 3 = 0
2x² + x + (-3) = 0
x = -b +/- √b² - 4ac
               2a
x = 1 + /- √1² - 4(2)(-3)
               2(2)
x = 1 + /- √1 +24
               4
x = 1 +/- √25
            4
x = 1 + /- 5
           4
x = 1 + 5       x = 1 - 5
         4                   4
x = 6             x = -4
      4                    4
x = 3             x = -1
      2
x = 1 1/2
x = 1 1/2       x = -1
