Q. Solve the quadratic by factoring.\newline2x29x6=10 2 x^{2}-9 x-6=-10 \newlineAnswer: x= x=
  1. Move Terms to One Side: Move all terms to one side of the equation to set it equal to zero.\newlineWe need to add 1010 to both sides of the equation to get a standard form of a quadratic equation.\newline2x29x6+10=02x^2 - 9x - 6 + 10 = 0\newline2x29x+4=02x^2 - 9x + 4 = 0
  2. Identify aa, bb, cc: Identify aa, bb, and cc in the quadratic equation 2x29x+42x^2 - 9x + 4. Compare 2x29x+42x^2 - 9x + 4 with ax2+bx+cax^2 + bx + c. a=2a = 2 bb00 bb11
  3. Find Multiplying Numbers: Find two numbers that multiply to aca*c (24=82*4 = 8) and add up to bb (9-9).\newlineWe are looking for two numbers that multiply to 88 and add up to 9-9.\newlineThe numbers are 1-1 and 8-8 because 18=8-1 * -8 = 8 and 1+8=9-1 + -8 = -9.
  4. Rewrite Middle Term: Rewrite the middle term of the quadratic equation using the two numbers found in Step 33.\newline2x29x+42x^2 - 9x + 4 can be rewritten by splitting the middle term into 1x-1x and 8x-8x.\newline2x21x8x+42x^2 - 1x - 8x + 4
  5. Factor by Grouping: Factor by grouping.\newlineGroup the first two terms and the last two terms.\newline(2x21x)+(8x+4)(2x^2 - 1x) + (-8x + 4)\newlineFactor out the greatest common factor from each group.\newlinex(2x1)4(2x1)x(2x - 1) - 4(2x - 1)
  6. Factor out Common Binomial: Factor out the common binomial factor.\newlineThe common binomial factor is (2x1)(2x - 1).\newlinex(2x1)4(2x1)x(2x - 1) - 4(2x - 1) can be factored as (2x1)(x4)(2x - 1)(x - 4).
  7. Set Factors Equal to Zero: Set each factor equal to zero and solve for xx.2x1=02x - 1 = 0 or x4=0x - 4 = 0For 2x1=02x - 1 = 0: Add 11 to both sides and then divide by 22.2x=12x = 1x=12x = \frac{1}{2}For x4=0x - 4 = 0: Add 44 to both sides.2x1=02x - 1 = 000
