2 x^{1} - x^{2} = - 3, 5 x^{1} + 7 x^{2} = 4

x = - 1, x = 3

Solution steps

2 x^{1} - x^{2} = - 3

Refine

2 x - x^{2} = - 3

Move

3

to the left side

2 x - x^{2} + 3 = 0

Write in the standard form

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

- x^{2} + 2 x + 3 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 2 \pm 2 ^{2} - 4 ( - 1 ) \cdot 3}{2 ( - 1 )}

2^{2} - 4 (- 1) \cdot 3 = 4

x_{1, 2} = \frac{- 2 \pm 4}{2 ( - 1 )}

Separate the solutions

x_{1} = \frac{- 2 + 4}{2 ( - 1 )}, x_{2} = \frac{- 2 - 4}{2 ( - 1 )}

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

x = \frac{- 2 - 4}{2 ( - 1 )} : 3

The solutions to the quadratic equation are:

x = - 1, x = 3

(\frac{- x ^{2}}{2}) + 15 = 11

x^{2} - 3 x + 2 = 1

a, f = a^{2} x + b

5 w^{2} - 20 w = 0

y^{2} - 3 y = 40
