Question

3x-x+y+36-xpower2+x​

Answer 1

Answer:

$3x - x + y + 36 - x {}^{2} + x \\ 2x + y + 36 - x {}^{2} + x \\ 2x + x + y + 36 - x {}^{2} \\ 3x + y + 36 - x {}^{2} \\ 39x + y - x {}^{2} \\ - x {}^{2} + 39x + y$

ok ok

Answer 2

Answer:

4x2 – 3x + 7

⇒ 4x2 – 3x + 7x°

∵ All the exponents of x are whole numbers.

∴ 4x2 – 3x + 7 is a polynomial in one variable.

(ii)

∵ All the exponents of y are whole numbers.

∴

is a polynomial in one variable.
