?
Step-by-step explanation:
Answer: 3n-6
Step-by-step explanation: You have to use the distributive property. 3 times n is 3n and 3 times -2 is -6.
Answer:
the answer to the question is 8x⁴- 5x²y² - 6y⁴
Step-by-step explanation:
the normal way of using BODMAS is apply to all polynomial equations.
subtracting -6x⁴- 3x²y² + 5y⁴ from 2x⁴ - 8x²y² - y⁴.
polynomial of the same degree is very easy to calculate. this equation is having the same degree of polynomial all through, therefore:
Applying Bracket to the equation
2x⁴ - 8x²y² - y⁴- ( -6x⁴- 3x²y² + 5y⁴)
Open the bracket
2x⁴ - 8x²y² - y⁴ +6x⁴+3x²y² - 5y⁴
collects the likes terms
2x⁴ +6x⁴- 8x²y² +3x²y² - 5y⁴ - y⁴
The final answer is =
8x⁴- 5x²y² - 6y⁴
To have infinitely many solutions they must describe the same line. So any multiple or fraction of the reference line would indeed describe the same line, and thus "intersect" at each and every of an infinite number of points.
2(x+y=4)
2x+2y=8 (is the same line as x+y=4)
