Find the Expanded Form (x-5)^2+(y-15)^2=4

${(x - 5)}^{2} + {(y - 15)}^{2} = 4$

Step 1

Simplify the left side ${(x - 5)}^{2} + {(y - 15)}^{2}$ .

Simplify each term.

Rewrite ${(x - 5)}^{2}$ as $(x - 5) (x - 5)$ .

$(x - 5) (x - 5) + {(y - 15)}^{2} = 4$

Expand $(x - 5) (x - 5)$ using the FOIL Method.

Apply the distributive property.

$x (x - 5) - 5 (x - 5) + {(y - 15)}^{2} = 4$

Apply the distributive property.

$x \cdot x + x \cdot - 5 - 5 (x - 5) + {(y - 15)}^{2} = 4$

Apply the distributive property.

$x \cdot x + x \cdot - 5 - 5 x - 5 \cdot - 5 + {(y - 15)}^{2} = 4$

Simplify and combine like terms.

Simplify each term.

Multiply $x$ by $x$ .

$x^{2} + x \cdot - 5 - 5 x - 5 \cdot - 5 + {(y - 15)}^{2} = 4$

Move $- 5$ to the left of $x$ .

$x^{2} - 5 \cdot x - 5 x - 5 \cdot - 5 + {(y - 15)}^{2} = 4$

Multiply $- 5$ by $- 5$ .

$x^{2} - 5 x - 5 x + 25 + {(y - 15)}^{2} = 4$

Subtract $5 x$ from $- 5 x$ .

$x^{2} - 10 x + 25 + {(y - 15)}^{2} = 4$

Rewrite ${(y - 15)}^{2}$ as $(y - 15) (y - 15)$ .

$x^{2} - 10 x + 25 + (y - 15) (y - 15) = 4$

Expand $(y - 15) (y - 15)$ using the FOIL Method.

Apply the distributive property.

$x^{2} - 10 x + 25 + y (y - 15) - 15 (y - 15) = 4$

Apply the distributive property.

$x^{2} - 10 x + 25 + y \cdot y + y \cdot - 15 - 15 (y - 15) = 4$

Apply the distributive property.

$x^{2} - 10 x + 25 + y \cdot y + y \cdot - 15 - 15 y - 15 \cdot - 15 = 4$

Simplify and combine like terms.

Simplify each term.

Multiply $y$ by $y$ .

$x^{2} - 10 x + 25 + y^{2} + y \cdot - 15 - 15 y - 15 \cdot - 15 = 4$

Move $- 15$ to the left of $y$ .

$x^{2} - 10 x + 25 + y^{2} - 15 \cdot y - 15 y - 15 \cdot - 15 = 4$

Multiply $- 15$ by $- 15$ .

$x^{2} - 10 x + 25 + y^{2} - 15 y - 15 y + 225 = 4$

Subtract $15 y$ from $- 15 y$ .

$x^{2} - 10 x + 25 + y^{2} - 30 y + 225 = 4$

Simplify the expression.

Add $25$ and $225$ .

$x^{2} - 10 x + y^{2} - 30 y + 250 = 4$

Move $- 10 x$ .

$x^{2} + y^{2} - 10 x - 30 y + 250 = 4$

Step 2

Subtract $4$ from both sides of the equation.

$x^{2} + y^{2} - 10 x - 30 y + 250 - 4 = 0$

Step 3

Subtract $4$ from $250$ .

$x^{2} + y^{2} - 10 x - 30 y + 246 = 0$
