Question

Subtract 5z3+7z2+2z-4 from -3z2+11z+12z3+13

Answer 1

❥︎ Correct Question :

Subtract 5z³ + 7z² + 2z - 4 from - 3z² + 11z + 12z³ + 13

❥︎ Answer :

$\textsf {(-3z² + 11z + 12z³ + 13) - (5z³ + 7z² + 2z - 4)}$

$\textsf{ (12z³ - 3z² + 11z + 13) - (5z³ + 7z² + 2z - 4)}$

$\textsf{ 12z³ - 3z² + 11z + 13 - 5z³ - 7z² - 2z + 4}$

$\textsf {= 7z³ - 10z² + 9z + 17}$

$\implies \textsf {Hence, the answer is 7z³ - 10z² + 9z + 17.}$
