Multiptly by -1 but sides to get,
Subtract 1 thus,
Then use quadradic formula.
im having trouble in changing subjects for equations, such as
4n-3nsquared= -1.. is there like a simple formula for changing the numbers around so it makes sense as in axsquared+bx+c=0?
I usually just do simple math to figure where each number goes like for 4n-3nsquared= -1, i usually think about 4-5=1 and rearrange it to make the equation make sense in the form of axsquared+bx+c=0...
This is for quadratics, so if the question is in the form of axsquared+bx+c=0, then its very easy to solve.
Can someone please help me with this?
Thanks in advance.
