Question

Multiply Use the ^ (shift 6) to indicate exponents.
a. (2x - ½)²

Answer 1

To multiply the expression (2x - ½)², use the formula for squaring a binomial: a² - 2ab + b². Plug in the values of a and b to get the simplified expression.

Step-by-step explanation:

To multiply the expression (2x - ½)², we use the formula for squaring a binomial, which is (a - b)² = a² - 2ab + b². In this case, a = 2x and b = ½. Plugging these values into the formula, we get:

(2x - ½)² = (2x)² - 2(2x)(½) + (½)²

Simplifying the expression, we have:

(2x - ½)² = 4x² - 2x + ¼
