Question

calcular o zero das funcoes a) y= x ao quadrado menos 5x+6 b) y=4x ao quadrado menos 4x+1

Answer 1

a) y = X^2 - 5X + 6

f(x) => f(0)
>>>>>>>>>
y = X^2 - 5X + 6

y = (0)^2 - 5(0) + 6

y = 0 - 0 + 6

y = 0 + 6

y = 6

b) y = 4X^2 - 4X + 1

f(x) => f (0)
>>>>>>>>>
y = 4X ^2 - 4X + 1

y = 4(0)^2 - 4(0) + 1

y = 4(0) - 0 + 1

y = 0 - 0 + 1

y = 0 + 1

y = 1
