Question

What is the solution for the equation 363-262-513-2?
5
2
?
Ob= -4 and b = 0
O b = -4
O b = 0 and b = 4
O b = 4

Answer 1

Answer:

O b = 0 and b = 4

Step-by-step explanation:

${ \tt{ \frac{5}{ {3b}^{3} - {2b}^{2} - 5 } = \frac{2}{ {b}^{3} - 2} }} \\ \\ { \tt{5( {b}^{3} - 2) = 2( {3b}^{3} - 2 {b}^{2} - 5)}} \\ { \tt{5 {b}^{3} - 10 = 6 {b}^{3} - 4 {b}^{2} - 10 }} \\ { \tt{ {b}^{3} - {4b}^{2} = 0 }} \\ { \tt{b {}^{2} ( {b}-4) = 0 }}$

• Either b² or (b - 4) is zero

${ \boxed{ \tt{b = 0 \: \: or \: \: b = 4}}}$
