Answer:
f(x) = (4x - 1)(2x + 1)
The zeros of the function are and .
Step-by-step explanation:
The given quadratic expression is 8x² - 2x - 3.
Now, the factorization of this quadratic expression gives:
f(x) = 8x² - 2x - 3
⇒ f(x) = 8x² - 6x + 4x - 3
⇒ f(x) = 2x(4x - 3) + 1(4x - 3)
⇒ f(x) = (4x - 1)(2x + 1)
Hence, the zeros of the function are and . (Answer)
The general form of an even number is 2n. So, odd number is 2n + 1 and 2n + 3.
Now, we have as the follows,
(2x + 1)(2x + 3) = 323
Or, 4x^2 + 6x + 2x + 3 = 323
Or, 4x^2 + 8x - 320 = 0
Or, x^2 + 2x - 80 = 0
Hence, the quadratic equation established is
