15x^2+14x-49=0\\\\
Terms:\\
a=15\ \ \ \ b=14\ \ \ \ c=-49\\
Quadratic\ Formula:\\\\
x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\
x=\dfrac{-14\pm\sqrt{196+2,940}}{30}\\\\
x=\dfrac{-14\pm\sqrt{3,136}}{30}\\\\
x=\dfrac{-14\pm56}{30}

Roots:\\\\
x'=\dfrac{-14+56}{30}\\\\
x'=\dfrac{42}{30}\\\\
x'=\dfrac{21}{15}\\\\
\boxed{x'=\dfrac{7}{5}}\\\\\\\\
x''=\dfrac{-14-56}{30}\\\\
x''=\dfrac{-70}{30}\\\\
\boxed{x''=\dfrac{-7}{3}}

15x² + 14 - 49 = 0
x = <u>-(14) +/- √((14)² - 4(15)(-49))</u>
                         2(15)
x = <u>-14 +/- √(196 + 2940)</u>
                     30
x = <u>-14 +/- √(3136)</u>
                 30
x = <u>-14 +/- 56</u>
             30
x = <u>-14 + 56</u>      x = <u>-14 - 56</u>
           30                     30
x = <u>42</u>               x = <u>-70</u>
      30                      30
x = 1.4              x = 2.33...
