4 x^{2} + 69 = 28 x

x = \frac{7}{2} + 5 i, x = \frac{7}{2} - 5 i

Solution steps

4 x^{2} + 69 = 28 x

Move

28 x

to the left side

4 x^{2} + 69 - 28 x = 0

Write in the standard form

a x^{2} + b x + c = 0

4 x^{2} - 28 x + 69 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 28 ) \pm ( - 28 ) ^{2} - 4 \cdot 4 \cdot 69}{2 \cdot 4}

Simplify

(- 28)^{2} - 4 \cdot 4 \cdot 69 : 85 i

x_{1, 2} = \frac{- ( - 28 ) \pm 8 5 i}{2 \cdot 4}

Separate the solutions

x_{1} = \frac{- ( - 28 ) + 8 5 i}{2 \cdot 4}, x_{2} = \frac{- ( - 28 ) - 8 5 i}{2 \cdot 4}

x = \frac{- ( - 28 ) + 8 5 i}{2 \cdot 4} : \frac{7}{2} + 5 i

x = \frac{- ( - 28 ) - 8 5 i}{2 \cdot 4} : \frac{7}{2} - 5 i

The solutions to the quadratic equation are:

x = \frac{7}{2} + 5 i, x = \frac{7}{2} - 5 i

x^{2} - x - 35 = - x + 1

4 x^{2} - 16 x - 33

x^{2} - 2 x - 24 = 0

y, x y - 3 x + 4 x^{2} = 7

y, x^{2} - x y + y^{2} = 7
