Question

Find the zeros of the function.
State the multiplicity of multiple zeros.
y = 7x³ - 7x

Answer 1

0, 1, -1

Explanation:

7x³ - 7x = 0

=> x(7x² - 7) = 0

=> 7x(x² - 1) = 0

=> x(x² - 1) = 0

=> x(x+1)(x-1) =0

=> x = 0 or x = -1 or x = 1

Answer 2

The zeros of the function are x = -3, x = 1, x = 3. The multiplicity of the zero x = 3 is 3.
