WebTo solve this, you would use the zero product property. If you make one of the parentheses equal to zero then the whole left side is equal to zero (because zero multiplied by anything is zero). So you'd set the first set of parentheses like so: (x-2)=0. Then to isolate "x", you would add 2 to both sides to get x=2. WebThe following are the suggested steps used to factor this type of “hard” trinomial. Step 1 : The basic strategy to factor this “hard” trinomial is to multiply the leading coefficient a a and the last coefficient c c to get a certain value called k k. …
