$a\left(\left(\sin\left(bs45\right)+\cos\left(45\right)\right)\frac{1}{x-1}- \left(\cos\left(45\right)-\sin\left(45\right)\right)\left(x^2-2x+1\right)\right)$
Learn how to solve special products problems step by step online. Expand the expression a((sin(bs45)+cos(45))1/(x-1)-(x^2+1*-2x+1)(cos(45)-sin(45))). Multiply 1 times -2. The sine of 45 equals \frac{\sqrt{2}}{2}. Multiply -1 times \frac{\sqrt{2}}{2}. The cosine of 45 equals \frac{\sqrt{2}}{2}.
