The required solution of the given equation rq² + 3qr + r² at r = 5 and q = 2 is 75.
Given that,
An equation rq² + 3qr + r² is given and has its solution at q = 2 and r = 5,
The simplified value of the given expression is to be evaluated.
Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in set of y. x is the independent variable while Y is the dependent variable.
The given expression is,
= rq² + 3qr + r²
The above-given equation has it a solution at q =2 and r = 5, so put values of q and r in the given equation.
= 5 * 2² + 3 * 2 * 5 + 5²
= 20 + 30 + 25
= 75
Thus the required solution of the given equation rq² + 3qr + r² at r = 5 and q = 2 is 75.
