Quais são os zeros(ou raízes) da função quadrática f(x) = x² + 3x - 4? Assinale a alternativa correta. *
faust18 [17]

Given:

The quadratic function is:

f(x)=x^2+3x-4

To find:

The zeros of the given quadratic function.

Solution:

We have,

f(x)=x^2+3x-4

Splitting the middle term, we get

f(x)=x^2+4x-x-4

f(x)=x(x+4)-1(x+4)

f(x)=(x+4)(x-1)

For zeros, f(x)=0.

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

x=-4,1

Therefore, the correct option is (b).
