Q. Factor completely.\newline2x23x+1 2 x^{2}-3 x+1 \newlineAnswer:
  1. Identify a,b,ca, b, c: Identify a,b,a, b, and cc in the quadratic expression 2x23x+12x^2 - 3x + 1. Compare 2x23x+12x^2 - 3x + 1 with ax2+bx+cax^2 + bx + c. a=2a = 2 b=3b = -3 c=1c = 1
  2. Find product and sum: Find two numbers whose product is aca*c (21=22*1 = 2) and whose sum is bb (3-3).\newlineWe need to find two numbers that multiply to 22 and add up to 3-3.\newlineThe numbers 1-1 and 2-2 satisfy these conditions because:\newline12=2-1 * -2 = 2\newline1+2=3-1 + -2 = -3
  3. Rewrite middle term: Rewrite the middle term 3x-3x using the two numbers found in Step 22.\newline2x23x+12x^2 - 3x + 1 can be rewritten as:\newline2x2x2x+12x^2 - x - 2x + 1
  4. Factor by grouping: Factor by grouping.\newlineGroup the terms into two pairs:\newline(2x2x)+(2x+1)(2x^2 - x) + (-2x + 1)\newlineFactor out the greatest common factor from each pair:\newlinex(2x1)1(2x1)x(2x - 1) - 1(2x - 1)
  5. Factor out common binomial: Factor out the common binomial factor.\newlineThe common binomial factor is (2x1)(2x - 1), so we factor it out:\newline(2x1)(x1)(2x - 1)(x - 1)
