A = x^{2} - 8 x + 15

x = 4 + A + 1, x = 4 - A + 1

Solution steps

A = x^{2} - 8 x + 15

Switch sides

x^{2} - 8 x + 15 = A

Move

A

to the left side

x^{2} - 8 x + 15 - A = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 8 ) \pm ( - 8 ) ^{2} - 4 \cdot 1 \cdot ( 15 - A )}{2 \cdot 1}

Simplify

(- 8)^{2} - 4 \cdot 1 \cdot (15 - A) : 2 A + 1

x_{1, 2} = \frac{- ( - 8 ) \pm 2 A + 1}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 8 ) + 2 A + 1}{2 \cdot 1}, x_{2} = \frac{- ( - 8 ) - 2 A + 1}{2 \cdot 1}

x = \frac{- ( - 8 ) + 2 A + 1}{2 \cdot 1} : 4 + A + 1

x = \frac{- ( - 8 ) - 2 A + 1}{2 \cdot 1} : 4 - A + 1

The solutions to the quadratic equation are:

x = 4 + A + 1, x = 4 - A + 1

52 + n = \frac{n ( n - 3 )}{2}

s, Y (s + 11) (s + 12) = U \cdot 7

(x - 5)^{2} = 45

v^{2} - 8 v - 1 = 8

c (x) = 1.2 x^{2} - 744 x + 134191
