Question

solve the following equation by factorisation 10x-1/x=3 by using splitting the middle term​

Answer 1

Answer:

Step-by-step explanation:

$10x-\frac1x=3\\\\10x^2-1=3x\\\\10x^2-3x-1=0\\\\10x^2-5x+2x-1=0\\\\5x(2x-1)+(2x-1)=0\\\\(2x-1)(5x+1)=0\\\\\Rightarrow 2x=1 \Rightarrow x=\frac12\\\\Or \ 5x=-1 \Rightarrow x=-\frac15$
