simplify (x-1)(1-x)

Solution

simplify

(x - 1) (1 - x)

- (x - 1)^{2}

Solution steps

(x - 1) (1 - x)

Simplify

1 - x : - (x - 1)

= (x - 1) (- (x - 1))

Apply rule:

a (- b) = - ab

(x - 1) (- (x - 1)) = - (x - 1) (x - 1)

= - (x - 1) (x - 1)

Apply exponent rule:

aa = a^{2}

- (x - 1) (x - 1) = - (x - 1)^{2}

= - (x - 1)^{2}

5 (a + h)^{2} - (a + h) + 3

\frac{5}{2} - \frac{1}{6}

- 5 x + x - 6 x^{3} - 4 - 5 + 6 x^{3} - 3 x^{3}

\frac{( 3 c + 2 )}{1} + \frac{c - 1}{c}

i^{7} (1 + i^{2})
