Q. Solve the equation 6x2+9x7=2 6 x^{2}+9 x-7=-2 to the nearest tenth.\newlineAnswer: x= x=
  1. Set Equation to Zero: First, we need to set the equation to zero by adding 22 to both sides.\newline6x2+9x7=26x^2 + 9x - 7 = -2\newline6x2+9x7+2=06x^2 + 9x - 7 + 2 = 0\newline6x2+9x5=06x^2 + 9x - 5 = 0
  2. Factor or Use Quadratic Formula: Next, we will attempt to factor the quadratic equation, but if it is not factorable, we will use the quadratic formula. The quadratic formula is x=b±b24ac2ax = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}, where a=6a = 6, b=9b = 9, and c=5c = -5.
  3. Calculate Discriminant: Calculate the discriminant b24acb^2 - 4ac to determine if there are real solutions.\newlineDiscriminant = 924(6)(5)9^2 - 4(6)(-5)\newlineDiscriminant = 81+12081 + 120\newlineDiscriminant = 201201\newlineSince the discriminant is positive, there are two real solutions.
  4. Apply Quadratic Formula: Now, apply the quadratic formula to find the solutions for xx.x=9±20126x = \frac{-9 \pm \sqrt{201}}{2\cdot 6}x=9±20112x = \frac{-9 \pm \sqrt{201}}{12}
  5. Calculate Solutions: Calculate the two solutions for xx.
    First solution:
    x=9+20112x = \frac{-9 + \sqrt{201}}{12}
    x9+14.17712x \approx \frac{-9 + 14.177}{12}
    x5.17712x \approx \frac{5.177}{12}
    x0.431x \approx 0.431

    Second solution:
    x=920112x = \frac{-9 - \sqrt{201}}{12}
    x914.17712x \approx \frac{-9 - 14.177}{12}
    x23.17712x \approx \frac{-23.177}{12}
    x1.931x \approx -1.931

    Round both solutions to the nearest tenth.
    First solution: x0.4x \approx 0.4
    Second solution: x=9+20112x = \frac{-9 + \sqrt{201}}{12}00
