Question

9x²+2y²+z from 7x²+2y²+3z
​

Answer 1

Answer:

Question 3: Divide 9x2y − 6xy + 12xy2 by −32xy. ... (ii), 15z3 − 20z2 + 13z − 12, 3z − 6. (iii), 6y5 − 28y3 + 3y2 + 30y ... Remainder is zero; therefore, z2 + 3 is a factor of z5 -9z. (vi) Remainder is ... (iii) 4x2 − 5, 4x4 + 7x2 + 15 (iv) 4 − z, 3z2 ...

Answer 2

Answer:

-2x²+2z

Step-by-step explanation:

7x²+2y²+3z-(9x²+2y²+z)

=7x²+2y²+3z-9x²-2y²-1z

=7x²-9x²+2y²-2y²+3z-1z

=-2x²+0+2z

=-2x²+2z
