Q. Factor completely.\newline5x2+75x+270 5 x^{2}+75 x+270 \newlineAnswer:
  1. Identify Terms: Identify the coefficients and constant term in the quadratic expression 5x2+75x+2705x^2 + 75x + 270. The coefficient of x2x^2 (a)(a) is 55, the coefficient of xx (b)(b) is 7575, and the constant term (c)(c) is 270270.
  2. Find GCF: Look for a greatest common factor (GCF) that can be factored out from all the terms in the expression.\newlineThe GCF of 55, 7575, and 270270 is 55.\newlineFactor out the GCF from the expression: 5(x2+15x+54)5(x^2 + 15x + 54).
  3. Factor Out GCF: Now, focus on factoring the quadratic expression inside the parentheses: x2+15x+54x^2 + 15x + 54. We need to find two numbers that multiply to give acac (5×54=2705 \times 54 = 270) and add up to bb (1515). The numbers that satisfy these conditions are 99 and 66, since 9×6=549 \times 6 = 54 and 9+6=159 + 6 = 15.
  4. Factor Quadratic Expression: Write the factored form of the quadratic expression using the numbers found in the previous step.\newlineThe factored form is 5(x+9)(x+6)5(x + 9)(x + 6).
