It’s 4am my insomniac ass can’t sleep so imma help u. pardon my handwriting To solve this equation by factorising .So like first make a cross lol
After u make a cross , look back to the equation.
Factorising is basically breaking down an equation into factors like (n+8) (n-3) etc.So we gonna break down this equation.

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
