Q. Factor completely.\newline3x2+8x3 3 x^{2}+8 x-3 \newlineAnswer:
  1. Identify Coefficients: Identify the coefficients of the quadratic expression.\newlineThe quadratic expression is 3x2+8x33x^2 + 8x - 3. Here, the coefficient of x2x^2 (a)(a) is 33, the coefficient of xx (b)(b) is 88, and the constant term (c)(c) is 3-3.
  2. Find Multiplying Numbers: Look for two numbers that multiply to acac (aa times cc) and add up to bb. We need to find two numbers that multiply to (3)(3)=9(3)(-3) = -9 and add up to 88. The numbers that satisfy these conditions are 99 and 1-1, because 9×(1)=99 \times (-1) = -9 and 9+(1)=89 + (-1) = 8.
  3. Rewrite Middle Term: Rewrite the middle term using the two numbers found in Step 22.\newlineWe can express 8x8x as 9xx9x - x. So, the expression 3x2+8x33x^2 + 8x - 3 can be rewritten as 3x2+9xx33x^2 + 9x - x - 3.
  4. Factor by Grouping: Factor by grouping.\newlineWe group the terms as follows: 3x2+9x3x^2 + 9x + x3 -x - 3. Now we factor out the common factors from each group. From the first group, we can factor out 3x3x, and from the second group, we can factor out 1 -1.\newlineThis gives us: 3x(x+3)1(x+3)3x(x + 3) - 1(x + 3).
  5. Factor Common Binomial: Factor out the common binomial factor.\newlineWe notice that (x+3)(x + 3) is a common factor in both terms. Factoring this out gives us: (x+3)(3x1)(x + 3)(3x - 1).
