Final answer:
The exact value of the expression -3 * (1.2)² is -4.32, obtained by first squaring 1.2 and then multiplying the result by -3.
Step-by-step explanation:
The exact value of -3 * (1.2)² is -4.32.To find the value of -3 * (1.2)², first square 1.2 to get 1.2 * 1.2 = 1.44. Then, multiply the result by -3: -3 * 1.44 = -4.32. This calculation represents a basic application of exponentiation followed by multiplication of a negative number. It doesn't involve the quadratic formula or any values for a, b, or c from quadratic
equations, which are irrelevant to this problem.
The value of -3 * (1.2)² is -4.32, so the answer is option a).To find the exact value, we start by squaring 1.2, which is 1.44. Then, we multiply it by -3, giving us -4.32.
