What is the solution of the following inequality?
3x^2−8x> 11

3x² - 8x > 11
3x² - 8x - 11 > 11 - 11
3x² - 8x - 11 > 0
x > -(-8) +/- √((-8)² - 4(3)(-11))
                        2(3)
x > 8 +/- √(64 + 132)
                   6
x > 8 +/- √(196)
              6
x > 8 +/- 14
            6
x > 8 + 14       x > 8 - 14
          6                     6
x > 20             x > -6
       6                     6
x > 3.33          x > -1

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
