3] FartA. Facto rising is a technique that is often used in Engineering to simplify equationsrexpressions prior to attempting to solve them. Facto rise the following three expressions as full}:r as possible a} 3x2 + 15x 2 b} fix 13x+1| 2 C} 3x 12x+4x16 Part B Facto risation can also he used to solve quadratic equations like the one in Part 2 if the numbers are simple enough. Used factorisation to solve the following quadratic equation 4:2219:+12= u Part C More complex quadratics are commonly solved by using the quadratic formula. Use the quadratic formula to solve the following q uadratic equation 3xz+ EDI8:0
