العربية

n (n - 24) = - 128

n = 16, n = 8

Solution steps

n (n - 24) = - 128

Expand

n (n - 24) : n^{2} - 24 n

n^{2} - 24 n = - 128

Move

128

to the left side

n^{2} - 24 n + 128 = 0

Solve with the quadratic formula

n_{1, 2} = \frac{- ( - 24 ) \pm ( - 24 ) ^{2} - 4 \cdot 1 \cdot 128}{2 \cdot 1}

(- 24)^{2} - 4 \cdot 1 \cdot 128 = 8

n_{1, 2} = \frac{- ( - 24 ) \pm 8}{2 \cdot 1}

Separate the solutions

n_{1} = \frac{- ( - 24 ) + 8}{2 \cdot 1}, n_{2} = \frac{- ( - 24 ) - 8}{2 \cdot 1}

n = \frac{- ( - 24 ) + 8}{2 \cdot 1} : 16

n = \frac{- ( - 24 ) - 8}{2 \cdot 1} : 8

The solutions to the quadratic equation are:

n = 16, n = 8
