Question 23338
<pre>Please help me to solve this equation:
1+2(x^2-4)=5-2x 
<font size = 4 color = "blue"><b>
1 + 2(x<sup>2</sup> - 4) = 5 - 2x

  1 + 2x<sup>2</sup> - 8 = 5 - 2x

      2x<sup>2</sup> - 7 =  5 - 2x
          + 7   +7
     -------------------
      2x<sup>2</sup>     = 12 - 2x
          -12  -12
     --------------------
     2x<sup>2</sup> - 12 =     -2x
        +2x         +2x
     --------------------
  2x<sup>2</sup> + 2x - 12 = 0

  2(x<sup>2</sup> + x - 6) = 0

2(x + 3)(x - 2) = 0         

x + 3 = 0 gives solution x = -3
x - 2 = 0 gives solution x = 2
