4 s^{2} - 17 s = 15

s = 5, s = - \frac{3}{4}

Decimal Notation

s = 5, s = - 0.75

Solution steps

4 s^{2} - 17 s = 15

Move

15

to the left side

4 s^{2} - 17 s - 15 = 0

Solve with the quadratic formula

s_{1, 2} = \frac{- ( - 17 ) \pm ( - 17 ) ^{2} - 4 \cdot 4 ( - 15 )}{2 \cdot 4}

(- 17)^{2} - 4 \cdot 4 (- 15) = 23

s_{1, 2} = \frac{- ( - 17 ) \pm 23}{2 \cdot 4}

Separate the solutions

s_{1} = \frac{- ( - 17 ) + 23}{2 \cdot 4}, s_{2} = \frac{- ( - 17 ) - 23}{2 \cdot 4}

s = \frac{- ( - 17 ) + 23}{2 \cdot 4} : 5

s = \frac{- ( - 17 ) - 23}{2 \cdot 4} : - \frac{3}{4}

The solutions to the quadratic equation are:

s = 5, s = - \frac{3}{4}

1 - (\frac{4}{6})^{5}

(- 3 x^{2} y^{2})^{3}

v^{2} - 9 v + 14

\frac{( 0.8 \cdot 1 0 ^{1} 0 )}{( 0.4 \cdot 1 0 ^{5} )}
