8x^2 + 21 = -59xadd 59x to both sides8x^2 + 59x + 21 = 0Well the factors of 21 are 3 and 7Possible factors of 8 are: 1&8,2&4,4&2,8&1so lets try the first one 3*1+7*8 = 3+56 = 59so(x+7)(8x+3) is the factored formI assumed the "answer" means that you are trying to find the zeroes.so the zeroes are -7 and -3/8
John Does answer is correct but just make sure that you show all of the work so that you fully understand what to do when you come across another problem like this!
