DOES ANYONE KNOW HOW TO DO QUADRATICS
bro quadratics are easy n shit i know but im having a massive brain fart and the steps im doing just dont work for me no more I NEED HELP BRO basically one of the many questions is (ill link it on photos) and basically i gotta use the formula “factorising to solve quadratic equations of the form a
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
