a.) If we were to S x dx by starting with the method of u sub, then a good 1-x choice for u could be: b.) If we were to evaluate J x 1 - x 2 dx by starting with the method of trig sub, then a good choice for x could be: c.) If we were to evaluate x , dx by starting with the method of partial fraction, 1-x then we should begin factoring the denominator. What is the decomposition of X - x
