To write the given quadratic equation to its vertex form, we first form a perfect square.
x² - 2x + 5 = 0
Transpose the constant to other side of the equation,
x² - 2x = -5
Complete the square in the left side of the equation,
x² - 2x + (-2/1(2))² = -5 + (-2/1(2))²
Performed the operation,
x² - 2x + 1 = -5 + 1
Factor the left side of the equation,
(x - 1)² = -4
Thus, the vertex form of the equation is,
<em> (x-1)² + 4 = 0</em>
Sorry but i am not exactly sure my work proved as wrong each time
Answer:
168 in cubed
Step-by-step explanation:
This should be correct if not tell me ill redo it :)
The previous length was 368 ft
the final length is 552 ft.
its a square so the distance between any two sides is the same as the length
The floor space increased by50% .
If 100%=368ft
then 50%=?
<u>5</u><u>0</u><u>. </u><u> </u> ×368ft
100
184 ft is the length increase in floor space
it is added to the original 368ft to get 552ft
