Solve (-6a-5)(4a^3)

Evaluate

(- 6 a - 5) (4 a^{3})

To find the roots of the expression,set the expression equal to 0

(- 6 a - 5) (4 a^{3}) = 0

Multiply the terms

(- 6 a - 5) \times 4 a^{3} = 0

Multiply the terms

4 a^{3} (- 6 a - 5) = 0

Elimination the left coefficient

a^{3} (- 6 a - 5) = 0

Separate the equation into 2 possible cases

a^{3} = 0 - 6 a - 5 = 0

The only way a power can be 0 is when the base equals 0

a = 0 - 6 a - 5 = 0

Solve the equation

More Steps

a = 0 a = - \frac{5}{6}

Solution

a_{1} = - \frac{5}{6}, a_{2} = 0

Alternative Form

a_{1} = - 0.8 \dot{3}, a_{2} = 0
