Find the x and y Intercepts (x+4)(-x+3)=y

$(x + 4) (- x + 3) = y$

Find the x-intercepts.

To find the x-intercept(s), substitute in $0$ for $y$ and solve for $x$ .

$(x + 4) (- x + 3) = 0$

Solve the equation.

If any individual factor on the left side of the equation is equal to $0$ , the entire expression will be equal to $0$ .

$x + 4 = 0$

$- x + 3 = 0$

Set $x + 4$ equal to $0$ and solve for $x$ .

Set $x + 4$ equal to $0$ .

$x + 4 = 0$

Subtract $4$ from both sides of the equation.

$x = - 4$

Set $- x + 3$ equal to $0$ and solve for $x$ .

Set $- x + 3$ equal to $0$ .

$- x + 3 = 0$

Solve $- x + 3 = 0$ for $x$ .

Subtract $3$ from both sides of the equation.

$- x = - 3$

Divide each term in $- x = - 3$ by $- 1$ and simplify.

Divide each term in $- x = - 3$ by $- 1$ .

$\frac{- x}{- 1} = \frac{- 3}{- 1}$

Simplify the left side.

Dividing two negative values results in a positive value.

$\frac{x}{1} = \frac{- 3}{- 1}$

Divide $x$ by $1$ .

$x = \frac{- 3}{- 1}$

Simplify the right side.

Divide $- 3$ by $- 1$ .

$x = 3$

The final solution is all the values that make $(x + 4) (- x + 3) = 0$ true.

$x = - 4, 3$

x-intercept(s) in point form.

x-intercept(s): $(- 4, 0), (3, 0)$

Find the y-intercepts.

To find the y-intercept(s), substitute in $0$ for $x$ and solve for $y$ .

$((0) + 4) (- (0) + 3) = y$

Solve the equation.

Rewrite the equation as $y = ((0) + 4) (- (0) + 3)$ .

$y = ((0) + 4) (- (0) + 3)$

Simplify $((0) + 4) (- (0) + 3)$ .

Add $0$ and $4$ .

$y = 4 (- (0) + 3)$

Multiply $- 1$ by $0$ .

$y = 4 (0 + 3)$

Add $0$ and $3$ .

$y = 4 \cdot 3$

Multiply $4$ by $3$ .

$y = 12$

y-intercept(s) in point form.

y-intercept(s): $(0, 12)$

List the intersections.

x-intercept(s): $(- 4, 0), (3, 0)$

y-intercept(s): $(0, 12)$
