Solve (9x^4)-(7x^5)

Evaluate

(9 x^{4}) - (7 x^{5})

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

(9 x^{4}) - (7 x^{5}) = 0

Multiply the terms

9 x^{4} - (7 x^{5}) = 0

Multiply the terms

9 x^{4} - 7 x^{5} = 0

Factor the expression

x^{4} (9 - 7 x) = 0

Separate the equation into 2 possible cases

x^{4} = 0 9 - 7 x = 0

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

x = 0 9 - 7 x = 0

Solve the equation

More Steps

x = 0 x = \frac{9}{7}

Solution

x_{1} = 0, x_{2} = \frac{9}{7}

Alternative Form

x_{1} = 0, x_{2} = 1. \dot{2} 8571 \dot{4}
