simplify ((1.99)^2-4)/((1.99)-2)

simplify

\frac{( 1.99 ) ^{2} - 4}{( 1.99 ) - 2}

3.99

Solution steps

\frac{1.9 9 ^{2} - 4}{( 1.99 ) - 2}

Apply rule:

(a) = a

(1.99) = 1.99

= \frac{1.9 9 ^{2} - 4}{1.99 - 2}

Factor

1.9 9^{2} - 4 : (1.99 + 2) (1.99 - 2)

= \frac{( 1.99 + 2 ) ( 1.99 - 2 )}{1.99 - 2}

\frac{( 1.99 + 2 ) ( 1.99 - 2 )}{1.99 - 2} = \frac{3.99 ( - 0.01 )}{- 0.01}

= \frac{3.99 ( - 0.01 )}{- 0.01}

Cancel the common factor:

- 0.01

= 3.99

32 a^{6} + 8 ab - 80 b^{2}

4 \cdot 1 0^{- 10}

(ab - mn) (mn + ab)
