Question

subtract
(iv) 3x³ - 5x² + 4x + 5 from 5x³ + 2x² + 3x + 6
(v) 2y³ - 2y²- 5 from -5a-3a + a³​

Answer 1

Step-by-step explanation:

${5x}^{3} + {2x}^{2} + 3x + 6- ({3x}^{3} - {5x}^{2} + 4x + 5) \\ {5x}^{3} + {2x}^{2} + 3x + 6 - {3x}^{3} + {5x}^{2} - 4x - 5 \\ now \: take \: x \: terms \: together \:$

${5x}^{3} - {3x}^{3} + {2x}^{2} + {5x}^{2} + 3x - 4x + 6 - 5$

${2x}^{3} + {7x}^{2} + 7x + 1$

${9x}^{5} + 7x + 1 \\ {16x}^{6} + 1$
