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
Answer:
16
Step-by-step explanation:
Perfect square in the quadratic from ax² + bx + c
You know an equation is perfect when:
2√(ax²)√(c) = bx
Substitute x² for ax² and 8x for bx. Then isolate c by doing the reverse operations.
2√(ax²)√(c) = bx
2√(x²)√(c) = 8x
2x√c = 8x Divide both sides by 2x
√c = 4 Square both sides to isolate c.
c = 16
The missing constant term is 16.
Check answer:
x² - 8x + 16
(x - 4)²
= (x - 4)(x - 4)
= x² - 4x - 4x + 16
= x² - 8x + 16
