8x² - 2x = 1

8x² - 2x - 1 = 0

a = 8, b = -2, c = -1

8x² - 2x - 1 = 0

a = 8, b = -2, c = -1

The product of the roots of 8x² - 2x = 1 is {1/2, -1/4)

8x² - 2x = 1

8x^2 - 2x - 1 = 0

(2x - 1)(4x + 1) = 0

x = 1/2 or x = -1/4

8x² - 2x = 1

8x^2 - 2x - 1 = 0

(2x - 1)(4x + 1) = 0

x = 1/2 or x = -1/4

x² + 6x - 55 = 0

(x + 11)(x - 5) = 0

x = -11 or x = 5

The product of the roots of x² + 6x - 55 = 0 is {-11, 5)

(x + 11)(x - 5) = 0

x = -11 or x = 5

The product of the roots of x² + 6x - 55 = 0 is {-11, 5)
