simplify (2(-0.51)+1)/(1/4-(-0.51^2))

simplify

\frac{2 ( - 0.51 ) + 1}{\frac{1}{4} - ( - 0.5 1 ^{2} )}

- 0.03920 \dots

Solution steps

\frac{2 ( - 0.51 ) + 1}{\frac{1}{4} - ( - 0.5 1 ^{2} )}

Remove parentheses:

(- a) = - a, - (- a) = a

= \frac{- 2 \cdot 0.51 + 1}{\frac{1}{4} + 0.5 1 ^{2}}

- 2 \cdot 0.51 + 1 = - 0.02

= \frac{- 0.02}{\frac{1}{4} + 0.5 1 ^{2}}

0.5 1^{2} = 0.2601

= \frac{- 0.02}{\frac{1}{4} + 0.2601}

Apply the fraction rule:

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

= - \frac{0.02}{\frac{1}{4} + 0.2601}

Convert element to a decimal form

\frac{1}{4} = 0.25

= - \frac{0.02}{0.25 + 0.2601}

Add the numbers:

0.25 + 0.2601 = 0.5101

= - \frac{0.02}{0.5101}

Divide the numbers:

\frac{0.02}{0.5101} = 0.03920 \dots

= - 0.03920 \dots
