A) 9ab/3a+b / a^2 - 6a/ a^2 - 4a -12

= 9a^3b - 36a^2b - 108ab / 3a^3 + a^2b - 18a^2 - 6ab

= 9a^2b - 36ab - 108b / 3a^2 + ab - 18a -6b

b) x^2 - 2xy - 3y^2/ x^2 - 9y^2 / 2x^2 - xy/ 2x^2+ xy- y^2

= 2x^4 - 3x^3y - 9x^2y^2 - xy^3 + 3y^4 /
2x^4 - x^3y - 18x^2y^2 + 9xy^3

1.Which expressions are polynomials? Select each correct answer. Pick more then one.

madreJ [45]

If all the power of the variables are greater than or equal to zero, then the expression is a valid polynomial.

So,

1.

$7x^{7}-x-5$

$35x^{2}$

$\frac{x}{5}+2$

are polynomials.

2.

$x^{2} -x\sqrt{2}$

y

2 + s

$4x^{2} +y$

are all polynomials.

3.

If the degree of the polynomial is 3, then it is a cubic polynomial. If the number of terms of a polynomial is 3, then it is a trinomial.

Hence, $-5x^{3}-4x+1$ is a cubic trinomial.

4.

The highest power is the degree.

Hence, degree of the polynomial is 2 + 4 = 6.
