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).

7x2 plus 7x5 = 49

(7x2 + 9)(4x - 1)
8=2^3 14=7x2 The LCM is 2^3x7=8x7=56 Doctor Chuck
You can take 7x2 out of both of those, leaving 5x4 and 1.
7x2=14x7=21x7=28x7=35x7=42x7=49x7=56x7=63
7x2- 63 = -35, when x equals 2
