If \displaystyle C=G-3FC=G−3F , find the trinomial that represents \displaystyle CC when \displaystyle F=2x^{2}+6x-5F=2x 2

+6x−5 and \displaystyle G=3x^{2}+4G=3x

2

+4

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex
