Find the Expanded Form (x+4)^2+(y-3)^2=25

${(x + 4)}^{2} + {(y - 3)}^{2} = 25$

Step 1

Simplify the left side ${(x + 4)}^{2} + {(y - 3)}^{2}$ .

Simplify each term.

Rewrite ${(x + 4)}^{2}$ as $(x + 4) (x + 4)$ .

$(x + 4) (x + 4) + {(y - 3)}^{2} = 25$

Expand $(x + 4) (x + 4)$ using the FOIL Method.

Apply the distributive property.

$x (x + 4) + 4 (x + 4) + {(y - 3)}^{2} = 25$

Apply the distributive property.

$x \cdot x + x \cdot 4 + 4 (x + 4) + {(y - 3)}^{2} = 25$

Apply the distributive property.

$x \cdot x + x \cdot 4 + 4 x + 4 \cdot 4 + {(y - 3)}^{2} = 25$

Simplify and combine like terms.

Simplify each term.

Multiply $x$ by $x$ .

$x^{2} + x \cdot 4 + 4 x + 4 \cdot 4 + {(y - 3)}^{2} = 25$

Move $4$ to the left of $x$ .

$x^{2} + 4 \cdot x + 4 x + 4 \cdot 4 + {(y - 3)}^{2} = 25$

Multiply $4$ by $4$ .

$x^{2} + 4 x + 4 x + 16 + {(y - 3)}^{2} = 25$

Add $4 x$ and $4 x$ .

$x^{2} + 8 x + 16 + {(y - 3)}^{2} = 25$

Rewrite ${(y - 3)}^{2}$ as $(y - 3) (y - 3)$ .

$x^{2} + 8 x + 16 + (y - 3) (y - 3) = 25$

Expand $(y - 3) (y - 3)$ using the FOIL Method.

Apply the distributive property.

$x^{2} + 8 x + 16 + y (y - 3) - 3 (y - 3) = 25$

Apply the distributive property.

$x^{2} + 8 x + 16 + y \cdot y + y \cdot - 3 - 3 (y - 3) = 25$

Apply the distributive property.

$x^{2} + 8 x + 16 + y \cdot y + y \cdot - 3 - 3 y - 3 \cdot - 3 = 25$

Simplify and combine like terms.

Simplify each term.

Multiply $y$ by $y$ .

$x^{2} + 8 x + 16 + y^{2} + y \cdot - 3 - 3 y - 3 \cdot - 3 = 25$

Move $- 3$ to the left of $y$ .

$x^{2} + 8 x + 16 + y^{2} - 3 \cdot y - 3 y - 3 \cdot - 3 = 25$

Multiply $- 3$ by $- 3$ .

$x^{2} + 8 x + 16 + y^{2} - 3 y - 3 y + 9 = 25$

Subtract $3 y$ from $- 3 y$ .

$x^{2} + 8 x + 16 + y^{2} - 6 y + 9 = 25$

Simplify the expression.

Add $16$ and $9$ .

$x^{2} + 8 x + y^{2} - 6 y + 25 = 25$

Move $8 x$ .

$x^{2} + y^{2} + 8 x - 6 y + 25 = 25$

Step 2

Subtract $25$ from both sides of the equation.

$x^{2} + y^{2} + 8 x - 6 y + 25 - 25 = 0$

Step 3

Combine the opposite terms in $x^{2} + y^{2} + 8 x - 6 y + 25 - 25$ .

Subtract $25$ from $25$ .

$x^{2} + y^{2} + 8 x - 6 y + 0 = 0$

Add $x^{2} + y^{2} + 8 x - 6 y$ and $0$ .

$x^{2} + y^{2} + 8 x - 6 y = 0$
