Solve by Factoring 3x(x-5)=7x^2-16x

$3 x (x - 5) = 7 x^{2} - 16 x$

Step 1

Move all the expressions to the left side of the equation.

Subtract $7 x^{2}$ from both sides of the equation.

$3 x (x - 5) - 7 x^{2} = - 16 x$

Add $16 x$ to both sides of the equation.

$3 x (x - 5) - 7 x^{2} + 16 x = 0$

Step 2

Simplify $3 x (x - 5) - 7 x^{2} + 16 x$ .

Simplify each term.

Apply the distributive property.

$3 x \cdot x + 3 x \cdot - 5 - 7 x^{2} + 16 x = 0$

Multiply $x$ by $x$ by adding the exponents.

Move $x$ .

$3 (x \cdot x) + 3 x \cdot - 5 - 7 x^{2} + 16 x = 0$

Multiply $x$ by $x$ .

$3 x^{2} + 3 x \cdot - 5 - 7 x^{2} + 16 x = 0$

Multiply $- 5$ by $3$ .

$3 x^{2} - 15 x - 7 x^{2} + 16 x = 0$

Subtract $7 x^{2}$ from $3 x^{2}$ .

$- 4 x^{2} - 15 x + 16 x = 0$

Add $- 15 x$ and $16 x$ .

$- 4 x^{2} + x = 0$

Step 3

Factor $x$ out of $- 4 x^{2} + x$ .

Factor $x$ out of $- 4 x^{2}$ .

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

Raise $x$ to the power of $1$ .

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

Factor $x$ out of $x^{1}$ .

$x (- 4 x) + x \cdot 1 = 0$

Factor $x$ out of $x (- 4 x) + x \cdot 1$ .

$x (- 4 x + 1) = 0$

Step 4

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

$x = 0$

$- 4 x + 1 = 0$

Step 5

Set $x$ equal to $0$ .

$x = 0$

Step 6

Set $- 4 x + 1$ equal to $0$ and solve for $x$ .

Set $- 4 x + 1$ equal to $0$ .

$- 4 x + 1 = 0$

Solve $- 4 x + 1 = 0$ for $x$ .

Subtract $1$ from both sides of the equation.

$- 4 x = - 1$

Divide each term in $- 4 x = - 1$ by $- 4$ and simplify.

Divide each term in $- 4 x = - 1$ by $- 4$ .

$\frac{- 4 x}{- 4} = \frac{- 1}{- 4}$

Simplify the left side.

Cancel the common factor of $- 4$ .

Cancel the common factor.

$\frac{- 4 x}{- 4} = \frac{- 1}{- 4}$

Divide $x$ by $1$ .

$x = \frac{- 1}{- 4}$

Simplify the right side.

Dividing two negative values results in a positive value.

$x = \frac{1}{4}$

Step 7

The final solution is all the values that make $x (- 4 x + 1) = 0$ true.

$x = 0, \frac{1}{4}$
