well they are binomials... \[(8x - 20)\times (2y - 30) = 0\] it just means that either 8x - 20 = 0 or 2y - 30 = 0 this will result in one binomial being zero... just solve for x and y
OpenStudy (anonymous):
how do i solve for x and y ?
OpenStudy (campbell_st):
well 8x = 20 divide by x 2y = 30 divide by 2
OpenStudy (anonymous):
so thw answer would be 15 ?
