The equation X squared plus Y squared minus 2X plus 7Y +1 equals zero can be written as which of the following equations

ad-work [718]

For this case we must write in algebraic symbology the expression described above:

We have an equation, then:

x squared plus y squared: $x ^ 2 + y ^ 2$

minus 2x plus 7y plus 1: $-2x + 7y + 1$

equals zero: $= 0$

We construct the equation:

$x ^ 2 + y ^ 2-2x + 7y + 1 = 0$

Answer:

$x ^ 2 + y ^ 2-2x + 7y + 1 = 0$
