First you have to look to see if you can isolate h. to do this you need to divide 2g on both sidesmaking the equation into f/2g=h.
just an extra little fact, we divide the 2g because it was multiplied as 2gh, to move it to the other side you do the opposite to it, therefore it being division :)
Answer: y = -3(x +
)² +
,
,
<u>Step-by-step explanation:</u>
First, you need to complete the square:
y = -3x² - 5x + 1
<u> -1 </u> <u> -1 </u>
y - 1 = -3x² - 5x
y - 1 = -3(x² + 
y - 1 + -3(
) = -3(x² +
+
)
↑ ↓ ↑
= 
y - 1 -
= -3(x +
)²
y -
-
= -3(x +
)²
y -
= -3(x +
)²
y = -3(x +
)² +
Now, it is in the form of y = a(x - h)² + k <em>where (h, k) is the vertex</em>
Vertex =

Answer:
Step-by-step explanation:
Solution:
Given dimensions of the rectangular sheet
Length = 28 cm
Breadth =22 cm
If the sheet is rolled to form a cylinder then the length becomes height and breadth becomes circumference of the base of a cylinder.
So Height of the cylinder (h)= 28 cm
Circumference of the base of a cylinder
Answer:
hello how are you nice to meet you
3x^2 − 6x + 2 - (<span>5x − 6)
= </span>3x^2 − 6x + 2 - 5x + 6
= 3x^2 - 11x + 8
hope it helps
