Is it necessary to use the formulas for special products of binomials to multiply these binomials? complete the explanation. yes/no. special products of binomials can/cannot be found by using foil instead of their formulas. in any case, the formulas would likely be faster to use.

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
