Question

Expand the following equation: (2x−3)2 Responses 4x2−9 4 x squared minus 9 4x2+9 4 x squared plus 9 2x2−12x+9 2 x squared minus 12 x plus 9 4x2−12x+9 4 x squared minus 12 x plus 9

Answer 1

The expanded form of the equation (2x−3)² is 4x² - 12x + 9.

Explanation:

To expand the equation (2x−3)², we can use the binomial expansion formula:

(a - b)² = a² - 2ab + b²

In this case, a = 2x and b = 3. Substituting these values into the formula, we get:

(2x−3)² = (2x)² - 2(2x)(3) + (3)²

Simplifying further:

(2x−3)² = 4x² - 12x + 9
