\left(\frac{2x}{2}-\frac{3-\sqrt{5}}{2}\right)\left(x-\frac{\sqrt{5}+3}{2}\right)
To add or subtract expressions, expand them to make their denominators the same. Multiply x times \frac{2}{2}.
\frac{2x-\left(3-\sqrt{5}\right)}{2}\left(x-\frac{\sqrt{5}+3}{2}\right)
Since \frac{2x}{2} and \frac{3-\sqrt{5}}{2} have the same denominator, subtract them by subtracting their numerators.
\frac{2x-3+\sqrt{5}}{2}\left(x-\frac{\sqrt{5}+3}{2}\right)
Do the multiplications in 2x-\left(3-\sqrt{5}\right).
\frac{2x-3+\sqrt{5}}{2}\left(\frac{2x}{2}-\frac{\sqrt{5}+3}{2}\right)
To add or subtract expressions, expand them to make their denominators the same. Multiply x times \frac{2}{2}.
\frac{2x-3+\sqrt{5}}{2}\times \frac{2x-\left(\sqrt{5}+3\right)}{2}
Since \frac{2x}{2} and \frac{\sqrt{5}+3}{2} have the same denominator, subtract them by subtracting their numerators.
\frac{2x-3+\sqrt{5}}{2}\times \frac{2x-\sqrt{5}-3}{2}
Do the multiplications in 2x-\left(\sqrt{5}+3\right).
\frac{\left(2x-3+\sqrt{5}\right)\left(2x-\sqrt{5}-3\right)}{2\times 2}
Multiply \frac{2x-3+\sqrt{5}}{2} times \frac{2x-\sqrt{5}-3}{2} by multiplying numerator times numerator and denominator times denominator.
\frac{\left(2x-3+\sqrt{5}\right)\left(2x-\sqrt{5}-3\right)}{4}
Multiply 2 and 2 to get 4.
\frac{4x^{2}-2x\sqrt{5}-6x-6x+3\sqrt{5}+9+2\sqrt{5}x-\left(\sqrt{5}\right)^{2}-3\sqrt{5}}{4}
Apply the distributive property by multiplying each term of 2x-3+\sqrt{5} by each term of 2x-\sqrt{5}-3.
