f(x)=2,x^2-7x+3=12

f (x) = 2, x^{2} - 7 x + 3 = 12

(x = \frac{7 + 85}{2}, x = \frac{7 - 85}{2}, f = 2 f = 2)

Solution steps

[f = 2 x^{2} - 7 x + 3 = 12]

Solve

x^{2} - 7 x + 3 = 12 : x = \frac{7 + 85}{2}, x = \frac{7 - 85}{2}

Plug the solutions

x = \frac{7 + 85}{2}, x = \frac{7 - 85}{2}

into

f = 2

For

f = 2

, subsitute

x

with

\frac{7 + 85}{2} : f = 2

For

f = 2

, subsitute

x

with

\frac{7 - 85}{2} : f = 2

Verify solutions by plugging them into the original equations

Therefore, the final solutions for

f = 2, x^{2} - 7 x + 3 = 12

are

(x = \frac{7 + 85}{2}, x = \frac{7 - 85}{2}, f = 2 f = 2)

x + y - z = 5, - x + y + z = 1

x + y = 7, x + z = 4 x + y + z

x + y = 10, x y = 16

4 y^{2} - 34 y + 289 = 0, x^{2} = 6

x^{2} + y^{2} - 12 x + 26 = 0, \frac{( x ^{2} )}{2} - y^{2} = \frac{7}{2}
