Which polynomial is in standard form?

Tamiku [17]

Answer:

D). $5x^7y^2+7x^6y^5-14x^3y^7+51x^2y^9$

Step-by-step explanation:

For better clarity let us re write the options

A). $2xy^3+3x^3y^4-4x^4y^5+9x^5y^6$

B). $8x^5-5y^4-2xy^5+x^2y$

C). $x^3y^2-3x^2y-9x^4y^3+11x$

D). $5x^7y^2+7x^6y^5-14x^3y^7+51x^2y^9$

To express polynomial with mixed variables in standard form, we begin by the highest coefficient of x to the smallest (we place high precedence on the coefficient x terms)

Answer:

$\large\boxed{-\dfrac{5}{8}+\dfrac{1}{4}=-\dfrac{3}{8}}$

Step-by-step explanation:

$-\dfrac{5}{8}+\dfrac{1}{4}=\dfrac{1}{4}+\left(-\dfrac{5}{8}\right)=\dfrac{1}{4}-\dfrac{5}{8}\\\\\text{find LCD:}\\\\8=2\cdot4,\ \text{therefore. LCD(4, 8) = 8}\\\\\dfrac{1}{4}=\dfrac{1\cdot2}{4\cdot2}=\dfrac{2}{8}\\\\\text{continuing}\\\\=\dfrac{2}{8}-\dfrac{5}{8}=\dfrac{2-5}{8}=-\dfrac{3}{8}$

jane and jill were simplifying the expression (2x2+x) +2(-x2+×) and obtained different answers . who is right and why?

Romashka [77]

Answer: who ever arrives at the answer x=0/3 =0 is correct

Step-by-step explanation:

Even though I need supporting details from the individual answers of Jane and Jill to pass my own judgment.

Given the expression

(2x²+x) +2(-x²+×)=0

Let's us open the bracket

2x²+x-2x²+2x=0

Collecting like terms

2x²-2x²+x+2x=0

3x=0

x=0/3

x=0
