simplify (2sqrt(x-1))(2sqrt(x+1))

simplify

(2 x - 1) (2 x + 1)

4 x - 1 x + 1

Solution steps

(2 x - 1) (2 x + 1)

Apply exponent rule:

a^{b} \cdot a^{c} = a^{b + c}

2 \cdot 2 = 2^{1 + 1}

= x - 1 \cdot 2^{1 + 1} x + 1

Add the numbers:

1 + 1 = 2

= x - 1 \cdot 2^{2} x + 1

2^{2} = 4

= 4 x - 1 x + 1

\frac{12 0 ^{3}}{3 !} e^{- 3}

x^{2} + 5 x x^{2} - 3

1.34 \cdot 1 0^{- 6}

x^{2} e^{- \frac{1}{2} (x - 2)^{2}}

1.786 \cdot 1 0^{- 6}
