Convert y=x^2-4x+5 to vertex form by completing the square

The vertex form will be:

Step-by-step explanation:

The equation of the vertex form of a quadratic equation is given by:

Where:

a is a coefficient

h is the x value of the vertex

k is the y value of the vertex

To completing the square we just need to add and subtract the square of the term with x divided by 2.

Finally, the vertex form will be:

I hope it helps you!

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

im guessing (23,14). hope this : )
