Brackets are very useful to math (especially in Especially in algebra). Example:8+(7x2)=208+7x2=30Still Cant understand? Keep reading.When you put the brackets at the 7x2 it makes u first figure out the answer of the digits in the brackets it self which is 14 so you convert the question to 8+14.
7x2 plus 7x5 = 49
7x2 + 68xy - 20y2
7x2- 63 = -35, when x equals 2
I suppose you mean, how do you factor it. 7x2 - 9x - 10 = (7x + 5)(x - 2).
