Show answer & explanation
Correct answer: A
Step-by-Step Solution
Simplify the Numerator:
Using the order of operations (BODMAS/PEMDAS), handle division and multiplication first:
(88 ÷ 8) * k = 11 * k = 11k
3 * 3 = 9
Numerator = 11k - 9
Simplify the Denominator:
6² = 36
7 * 5 = 35
Denominator = 36 - 35 + k² = 1 + k²
Set up the equation:
(11k - 9) / (1 + k²) = 1
Solve the quadratic equation:
Multiply both sides by (1 + k²):
11k - 9 = 1 + k²
Rearrange the terms into a standard quadratic form (ax² + bx + c = 0):
k² - 11k + 10 = 0
Factor the quadratic equation:
We need two numbers that multiply to 10 and add up to -11. Those numbers are -1 and -10.
(k - 1)(k - 10) = 0
Therefore, the possible values for k are 1 and 10.
