Question

Find all the zeros of the quadratic function y=x^(2)-5x+4

Answer 1

Zeros: 1, 4

Explanation:

y = x² - 5x + 4

degree: 2

two zeros

y = x² - 5x + 4

x² - 5x + 4 = 0

(x² - 1x) (-4x + 4) = 0

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

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

x - 4 = 0, x - 1 = 0

+4 +4 +1 +1

----------------------------

x = 4, x = 1

Zeros: 1, 4

Zeros in factored form: (x - 1)(x - 4)

I hope this helps!
