Answer:
a.) 1.60x^2y^2 2.(x-6)(x+1) 1.one way to find the least common multiple of two numbers is to first list the prime factors. 2.factoring quadratic equation ang factoring difference of two squares. b.) 1. to add or subtract ratinal expressions with unlike denomirators first find the LCM of the denomirators.the LCM of the denomirators of fraction or rational expressions is also called least common denomirator or LCD. 2.a rational expressions is simply a quatient of two nomials,or in other words it is fraction whose numerator and denomirator are polynomials. b.)perform the indicated opiration and answer the question that following 1. 4xy-x-y/xy 2. 10x+3/6x^2+15x+9 3. x^2-11x/x^2-8 4. x+12/2x^3-13x^2+3x+18 soryy yan lang kaya kong masaagot sana makatulong
