Ax² + bx + c = 0
2x² + x - 3 = 0
2x² + x + (-3) = 0
x = <u>-b +/- √b² - 4ac</u>
               2a
x = <u>1 + /- √1² - 4(2)(-3)</u>
               2(2)
x = <u>1 + /- √1 +24</u>
               4
x = <u>1 +/- √25
</u>            4<u>
</u>x = <u>1 + /- 5
</u>           4<u>
</u>x = <u>1 + 5</u>       x = <u>1 - 5
</u>         4      <u> </u>             4<u>
</u>x = <u>6</u>             x = <u>-4</u>
      4                    4
x = <u>3</u>             x = -1
      2
x = 1 1/2
x = 1 1/2       x = -1

Vincent has cut three pieces of rope to complete a science project. two pieces are of equal length. the third piece is one-quart
maks197457 [2]
Let the length of the 2 equal pieces be x m. Then the length of the third piece = 0.25x m.
So we have the equation:-

2x + 0.25x = 54

x  = 54 / 2.25 =  24  


So the length of the 3 pieces are 24,24 and 6 meters.
