a^{2} - 10 a + 25 = 49

a = 12, a = - 2

Solution steps

a^{2} - 10 a + 25 = 49

Move

49

to the left side

a^{2} - 10 a - 24 = 0

Solve with the quadratic formula

a_{1, 2} = \frac{- ( - 10 ) \pm ( - 10 ) ^{2} - 4 \cdot 1 \cdot ( - 24 )}{2 \cdot 1}

(- 10)^{2} - 4 \cdot 1 \cdot (- 24) = 14

a_{1, 2} = \frac{- ( - 10 ) \pm 14}{2 \cdot 1}

Separate the solutions

a_{1} = \frac{- ( - 10 ) + 14}{2 \cdot 1}, a_{2} = \frac{- ( - 10 ) - 14}{2 \cdot 1}

a = \frac{- ( - 10 ) + 14}{2 \cdot 1} : 12

a = \frac{- ( - 10 ) - 14}{2 \cdot 1} : - 2

The solutions to the quadratic equation are:

a = 12, a = - 2

(\frac{- 5 b ^{3}}{a})^{3}

t^{2} + 24 t - 25

5 - x > 7

5 x - 9 + 3 (3 x + 3) = - 2 (x + 2)
