Mathematics
1 answer:
hoa [83]2 years ago
5 0

Answer:

0 and 4

Step-by-step explanation:

y = x^2 - 4x can be factored as follows:  y = x(x - 4).

We find the zeros by setting this factored form equal to zero and solving for x:

x(x - 4) = 0, or x = 0, or x = 4.

The two zeros of this function are 0 and 4.

I need to show how to find these solutions 1/4 and 3/4 by completing the square!
Arlecino [84]

Answer:

See explanation, and ask for more details if unclear!

Step-by-step explanation:

The perfect square of this equation is x^2-x+\frac{1}{4}, since the square would be (x-\frac{1}{2})^2. 1/4=4/16, meaning that you can set up the equation in the following way:

(x^2-x+\frac{1}{4})-\frac{1}{16}=0

(x-\frac{1}{2})^2=\frac{1}{16}

Take the square root of both sides:

x-\frac{1}{2}=\pm \frac{1}{4}

Add 1/2 to both sides:

x=\frac{1}{2}\pm \frac{1}{4}=\frac{3}{4}, \frac{1}{4}. Hope this helps!
