Q. Solve the quadratic by factoring.\newline3x211x=4x4 3 x^{2}-11 x=-4 x-4 \newlineAnswer: x= x=
  1. Write Standard Form: Write the quadratic equation in standard form by moving all terms to one side of the equation.\newlineMove 4x-4x and 4-4 to the left side to get 3x211x+4x+4=03x^2 - 11x + 4x + 4 = 0.\newlineCombine like terms to get 3x27x+4=03x^2 - 7x + 4 = 0.
  2. Identify Coefficients: Identify aa, bb, and cc in the quadratic equation 3x27x+43x^2 - 7x + 4.a=3a = 3, b=7b = -7, c=4c = 4.
  3. Find Multiplying Numbers: Find two numbers that multiply to aca*c (34=123*4 = 12) and add up to bb (7-7).\newlineThe numbers are 3-3 and 4-4 because 34=12-3 * -4 = 12 and 3+4=7-3 + -4 = -7.
  4. Split Middle Term: Rewrite the quadratic equation by splitting the middle term using the two numbers found in Step 33. 3x23x4x+4=03x^2 - 3x - 4x + 4 = 0.
  5. Factor by Grouping: Factor by grouping.\newlineGroup the first two terms and the last two terms: (3x23x)(4x4)=0(3x^2 - 3x) - (4x - 4) = 0.\newlineFactor out the common factor from each group: 3x(x1)4(x1)=03x(x - 1) - 4(x - 1) = 0.
  6. Factor Common Binomial: Factor out the common binomial factor (x1)(x - 1).(3x4)(x1)=0(3x - 4)(x - 1) = 0.
  7. Set Factors Equal: Set each factor equal to zero and solve for xx.3x4=03x - 4 = 0 or x1=0x - 1 = 0.For 3x4=03x - 4 = 0, add 44 to both sides to get 3x=43x = 4, then divide by 33 to get x=43x = \frac{4}{3}.For x1=0x - 1 = 0, add 11 to both sides to get 3x4=03x - 4 = 000.
