2x^{2}-x-1=2\left(x-1\right)\times \left(\frac{2x+1}{2}\right) Add \frac{1}{2} to x by finding a common denominator and adding the numerators. Then reduce the fraction to lowest terms if possible.
Question from dana, a student: I don't know what is 2xy what does that mean? is it 2x+2y or 2x times y Please help! thank you for your time!! :)
So now you can multiply what are the same. You can multiply the coefficients together and the x variables together as follows: 2 × 2 = 4. x × x = x2. Then you put the answers together and make the multiplication sign invisible again to get the following answer: 2x × 2x = 4x2. What is 2x times 3x.
