Q. Factor the trinomial:\newline3x2+5x+2 3 x^{2}+5 x+2 \newlineAnswer:
  1. Identify coefficients: Identify the coefficients of the trinomial.\newlineThe trinomial is 3x2+5x+23x^2 + 5x + 2. Here, the coefficient of x2x^2 (a)(a) is 33, the coefficient of xx (b)(b) is 55, and the constant term (c)(c) is 22.
  2. Find two numbers: Find two numbers that multiply to acac (3×2=63 \times 2 = 6) and add up to bb (55).\newlineWe need to find two numbers that multiply to 66 and add up to 55. The numbers 33 and 22 satisfy these conditions because 3×2=63 \times 2 = 6 and 3+2=53 + 2 = 5.
  3. Rewrite middle term: Rewrite the middle term using the two numbers found in Step 22.\newlineWe can express 5x5x as 3x+2x3x + 2x. So, the trinomial becomes 3x2+3x+2x+23x^2 + 3x + 2x + 2.
  4. Factor by grouping: Factor by grouping.\newlineGroup the terms into two pairs: (3x2+3x)(3x^2 + 3x) and (2x+2)(2x + 2).\newlineFactor out the greatest common factor from each pair.\newlineFrom the first pair, we can factor out 3x3x, giving us 3x(x+1)3x(x + 1).\newlineFrom the second pair, we can factor out 22, giving us 2(x+1)2(x + 1).
  5. Factor common binomial: Factor out the common binomial factor.\newlineBoth groups have a common factor of (x+1)(x + 1). Factor this out to get the final factored form.\newlineThe factored form is (3x+2)(x+1)(3x + 2)(x + 1).
