Question 1168781
Mr mobile legends want to take a table for his friends which has an area of 10 square meters. the length of the table has to 3 meters longer than the width. find the width and length of the table
solution 
Let width is x mtrs 
length will be  x+3
area=lenghtxwidth
x(x+3)=10
x^2+3x-10=0
(x+5)(x-2)=0
x=-5 or x=2 width can  not be negative 
so x=2 
length  will be 5 mtrs
