Solve (x-7(x-7)) - ScanMath

Question

Simplify the expression

- 6 x + 49

Evaluate

x - 7 (x - 7)

Expand the expression

More Steps

Calculate

- 7 (x - 7)

Apply the distributive property

- 7 x - (- 7 \times 7)

Multiply the numbers

- 7 x - (- 49)

If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses

- 7 x + 49

x - 7 x + 49

Solution

More Steps

Evaluate

x - 7 x

Collect like terms by calculating the sum or difference of their coefficients

(1 - 7) x

Subtract the numbers

- 6 x

- 6 x + 49

Show Solution

Find the roots

x = \frac{49}{6}

Alternative Form

x = 8.1 \dot{6}

Evaluate

(x - 7 (x - 7))

To find the roots of the expression,set the expression equal to 0

x - 7 (x - 7) = 0

Collect like terms by calculating the sum or difference of their coefficients

(1 - 7) x

Subtract the numbers

- 6 x

- 6 x + 49

- 6 x + 49 = 0

Move the constant to the right-hand side and change its sign

- 6 x = 0 - 49

Removing 0 doesn't change the value,so remove it from the expression

- 6 x = - 49

Change the signs on both sides of the equation

6 x = 49

Divide both sides

\frac{6 x}{6} = \frac{49}{6}

Solution

x = \frac{49}{6}

Alternative Form

x = 8.1 \dot{6}
