simplify (5+sqrt(5^2-(4)(-2)(6)))/(2(-2))

simplify

\frac{5 + 5 ^{2} - ( 4 ) ( - 2 ) ( 6 )}{2 ( - 2 )}

- \frac{5 + 73}{4}

Decimal Notation

- 3.38600 \dots

Solution steps

\frac{5 + 5 ^{2} - ( 4 ) ( - 2 ) ( 6 )}{2 ( - 2 )}

- (4) (- 2) (6) = - 4 (- 2) \cdot 6

= \frac{5 + 5 ^{2} - 4 ( - 2 ) \cdot 6}{2 ( - 2 )}

5^{2} - 4 (- 2) \cdot 6 = 73

= \frac{5 + 73}{2 ( - 2 )}

Multiply the numbers:

2 (- 2) = - 4

= \frac{5 + 73}{- 4}

Apply the fraction rule:

\frac{a}{- b} = - \frac{a}{b}

= - \frac{5 + 73}{4}

- 15 x^{3} y^{5} (- 11 y^{4})

- \frac{1}{6} + \frac{1}{4}

lo g_{7} (a) - lo g_{7} (x) + lo g_{7} (4)

- 5 i^{1237}
