Question

4x (power 4) - 2 x (power 3) - 10 x + 13 x - 6 by (2 x + 3)​

Answer 1

Answer:

IVU, Find the LCM of the following set of the numbers by the common division method. b) 25, 45, 30 ​

Answer 2

$\frac{4 {x}^{4} - 2 {x}^{3} - 10 {x}^{2} + 13x - 6 }{2x + 3} = \\ 2 {x}^{3} - 4 {x}^{2} + x + 5 - \frac{21}{2x + 3}$

OR after factorisation

$= - \frac{21}{2x + 3} + 2(x - (\frac{ 4 - \sqrt[3]{ 242 - 6 \sqrt{1599} } - \sqrt[3]{ 242 + 6 \sqrt{1599} } }{6}) )(x - ( \frac{4 + \sqrt[3]{242 - 6 \sqrt{1599} } + \sqrt[3]{242 + 6 \sqrt{1599} } + \sqrt{3}i ( \sqrt[3]{242 + 6 \sqrt{1599} } - \sqrt[3]{242 - 6 \sqrt{1599} } ) }{12} ))(x - (\frac{4 + \sqrt[3]{242 - 6 \sqrt{1599} } + \sqrt[3]{242 + 6 \sqrt{1599} } + \sqrt{3} i( \sqrt[3]{242 - 6 \sqrt{1599} } - \sqrt[3]{242 + 6 \sqrt{1599} } ) }{12} ))$
