Answer

2x2−24x+722x^2 - 24x + 72

Step-by-step solution

2 steps
  1. Expand the squared term (x−6)2(x-6)^2.

    We use the formula (a−b)2=a2−2ab+b2(a-b)^2 = a^2 - 2ab + b^2. Here, a=xa=x and b=6b=6.

    (x−6)2=x2−2(x)(6)+62(x-6)^2 = x^2 - 2(x)(6) + 6^2 (x−6)2=x2−12x+36(x-6)^2 = x^2 - 12x + 36
  2. Multiply the expanded expression by 2.

    2(x2−12x+36)=2(x2)−2(12x)+2(36)2(x^2 - 12x + 36) = 2(x^2) - 2(12x) + 2(36) 2(x2−12x+36)=2x2−24x+722(x^2 - 12x + 36) = 2x^2 - 24x + 72

    The expanded form is:

    2x2−24x+722x^2 - 24x + 72
