What is f(x)=x^2-2x+3,f(x)=-2x+12 ?

The solution to f(x)=x^2-2x+3,f(x)=-2x+12 is

Popular >

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

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

(x = 3, x = - 3, f = 6 f = 18)

Solution steps

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

Subtract the equations

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

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

Simplify

0 = x^{2} - 9

Solve

0 = x^{2} - 9 : x = 3, x = - 3

Plug the solutions

x = 3, x = - 3

into

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

For

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

, subsitute

x

with

3 : f = 6

For

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

, subsitute

x

with

- 3 : f = 18

Verify solutions by plugging them into the original equations

Therefore, the final solutions for

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

are

(x = 3, x = - 3, f = 6 f = 18)

x^{2} + y^{2} = 2, 5 x + y = 5

4 x^{2} + y = 10, 0 yy + 9 = 9 (x + 1)

2 x + 3 y = 7, (a - b) x + (a + b) y = 3 a + b - 2

x^{2} + 2 y^{2} = 54, 2 x - y = - 9

x - 3 y = 3, - x + 3 y = - 3
