THIS IS THE ONE PART OF ALGEBRA THAT I'M ACTUALLY GOOD AT! This is literally what I learnt in my first year of middle school TvT So, 1) 2n²-15n+7=0 => 2n²-14n-n+7= 0 (Middle term split) => 2n(n-7)-1(n-7)=0 (Taking out common terms) => (n-7)(2n-1)=0 (Factorization) ∴ Either : (n-7)=0 =>n=7 OR: 2n-1=0 =>2n=1 =>n=1/2=0.5 A) 7 or 0.5 2) 3x²+1......   1 reply

Girl I just started pre calc and my last years teacher dug factoring so hard into our brains I can do it in my sleep now   2 reply

this reminds me i have a test of math this friday.   1 reply

using the first question as an example, 2n^2 -15n + 7 = 0 (2n - 1)(n - 7) = 0 2n - 1 = 0 and n - 7 = 0 therfore n = 1/2 and n = 7 hope that helps   1 reply
