Q. Factor as the product of two binomials.\newlinex23x10=x^{2}-3x-10=
  1. Identify quadratic trinomial: Identify the quadratic trinomial and its structure.\newlineThe given expression is x23x10x^2 - 3x - 10, which is in the standard form of a quadratic trinomial ax2+bx+cax^2 + bx + c, where a=1a = 1, b=3b = -3, and c=10c = -10.
  2. Determine factors of constant term: Determine the factors of the constant term cc that add up to the coefficient bb.\newlineWe need to find two numbers that multiply to 10-10 (the constant term) and add up to 3-3 (the coefficient of xx). The numbers that satisfy these conditions are 5-5 and +2+2.
  3. Rewrite middle term: Rewrite the middle term using the numbers found in Step 22.\newlineWe can express 3x-3x as 5x+2x-5x + 2x, which are the terms that come from the factors found in Step 22.\newlineSo, x23x10x^2 - 3x - 10 becomes x25x+2x10x^2 - 5x + 2x - 10.
  4. Factor by grouping: Factor by grouping.\newlineGroup the terms into two pairs: (x25x)(x^2 - 5x) and (2x10)(2x - 10).\newlineFactor out the greatest common factor from each pair.\newlineFrom the first pair, we can factor out an xx, giving us x(x5)x(x - 5).\newlineFrom the second pair, we can factor out a 22, giving us 2(x5)2(x - 5).\newlineNow we have x(x5)+2(x5)x(x - 5) + 2(x - 5).
  5. Factor out common binomial factor: Factor out the common binomial factor.\newlineThe common binomial factor is (x5)(x - 5).\newlineFactor this out to get (x5)(x+2)(x - 5)(x + 2) as the product of two binomials.
