Answer:
x = -1 and x = 3
Step-by-step explanation:
f(x)= x^2-2x-3
f(x) = (x + 1) (x - 3)
Therefore, x = -1 and x = 3
The zeroes of the quadratic function f(x) = x² + 2x - 3 will be 1 and negative 3.
What is a factorization?
It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
The quadratic equation is given as ax² + bx + c = 0. Then the degree of the equation will be 2.
The quadratic equation is given below.
f(x) = x² + 2x - 3
Then the factor of the quadratic equation will be
f(x) = x² + 2x - 3
f(x) = x² + 3x - x - 3
f(x) = x(x + 3) - 1(x + 3)
f(x) = (x + 3)(x - 1)
The zeroes of the function will be
f(x) = 0
(x + 3)(x - 1) = 0
x = 1, -3
Then the zeroes of the quadratic function f(x) = x² + 2x - 3 will be 1 and negative 3.
