Q. Solve the quadratic by factoring.\newline3x211x6=4x 3 x^{2}-11 x-6=-4 x \newlineAnswer: x= x=
  1. Move Terms to One Side: Move all terms to one side of the equation to set the equation to zero. 3x211x6=4x3x^2 - 11x - 6 = -4x becomes 3x211x+4x6=03x^2 - 11x + 4x - 6 = 0, which simplifies to 3x27x6=03x^2 - 7x - 6 = 0.
  2. Identify Coefficients: Identify aa, bb, and cc in the quadratic equation 3x27x63x^2 - 7x - 6.a=3a = 3, b=7b = -7, c=6c = -6.
  3. Find Multiplying Numbers: Find two numbers that multiply to aca*c (36=183*-6 = -18) and add up to bb (7-7).\newlineThe numbers 9-9 and 22 multiply to 18-18 and add up to 7-7.
  4. Split Middle Term: Rewrite the quadratic equation by splitting the middle term using the numbers found in Step 33. 3x29x+2x6=03x^2 - 9x + 2x - 6 = 0.
  5. Factor by Grouping: Factor by grouping.\newlineGroup the first two terms and the last two terms: (3x29x)+(2x6)=0(3x^2 - 9x) + (2x - 6) = 0.\newlineFactor out the common factors: 3x(x3)+2(x3)=03x(x - 3) + 2(x - 3) = 0.
  6. Factor Common Binomial: Factor out the common binomial factor (x3)(x - 3).(3x+2)(x3)=0(3x + 2)(x - 3) = 0.
  7. Set Factors Equal: Set each factor equal to zero and solve for xx.3x+2=03x + 2 = 0 or x3=0x - 3 = 0.For 3x+2=03x + 2 = 0, x=23x = -\frac{2}{3}.For x3=0x - 3 = 0, x=3x = 3.
