Solve by factoring 2x squared -6 = x squared+48

Mathematics
1 answer:
Kitty [74]4 years ago

x = ± 3√6

2x² - 6 = x² + 48 ( subtract x² from both sides )

x² - 6 = 48 ( add 6 to both sides )

x² = 54 ( take the square root of both sides )

x = ± √54 = ± 3√6

Answer:

C(C^3 + 8C^2 -3C -7)

Step-by-step explanation:

(-3C^4-5C^2-7C)+(4C^4+8C^3+2C^2)  

(-3C^4 +4C^4)+8C^3 + ( -5C^2 +2C^2)  -7C  [Combine like terms]

C^4 + 8C^3 -3C^2 -7C                                     [Simplify]

HELP I NEED THIS UNLESS I WANT TO FAIL ALGEBRA
Vladimir79 [104]

Answer:

H. x = 1 , slope is undefined

Step-by-step explanation:

The slope of a vertical line is always undefined.

If you think about it, no matter what y value you use, the x will always be 1 (In this equation). Such as:

(1, 5)

(1, 8)

(1, -12914)

(1, 272)

With x always being one, it forms a vertical line parallel to the y-axis
