simplify (i-1)^2+2/((i-1)^2)

simplify

(i - 1)^{2} + \frac{2}{( i - 1 ) ^{2}}

- i

Solution steps

(i - 1)^{2} + \frac{2}{( i - 1 ) ^{2}}

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

\frac{2}{( i - 1 ) ^{2}} = \frac{2 i}{2}

= - 2 i + \frac{2 i}{2}

Cancel the common factor:

2

= - 2 i + i

Add similar elements:

- 2 i + i = - i

= - i

\frac{5}{4} \cdot \frac{1}{2}

4 = x - 10

4 (12 x + 14) \leq 4 - 15 x

49 u^{2} - 28 u + 4

(\frac{2 x}{y})^{5}
