at simple interest. If Annu wants to repay the loan after 3 years ,which offer

should she choose for paying minimum interest ?​

Answer 1

Answer:

sister

Step-by-step explanation:

Calculating interest on a car, personal or home loan

• Divide your interest rate by the number of payments you'll make in the year (interest rates are expressed annually). ...

• Multiply it by the balance of your loan, which for the first payment, will be your whole principal amount.

Answer 2

Answer:

This implies that

x2+2ax=4x−4a−13

or

x2+2ax−4x+4a+13=0

or

x2+(2a−4)x+(4a+13)=0

Since the equation has just one solution instead of the usual two distinct solutions, then the two solutions must be same i.e. discriminant = 0.

Hence we get that

(2a−4)2=4⋅1⋅(4a+13)

or

4a2−16a+16=16a+52

or

4a2−32a−36=0

or

a2−8a−9=0

or

(a−9)(a+1)=0

So the values of a are −1 and 9.
