A kite of area 40 m squarehas one diagonal 2 m longer than the other. Find the length of the diagonal

Step-by-step explanation:

Let d1 be the first diagonal and d2 be the second diagonal.

Given

Area = 40 square meters

And one diagonal is 2 meter longer than other

The formula for area of kite is;

Putting the known values

The expression is a quadratic polynomial

Factorizing

As the value of length cannot be negative so discarding the negative value

Hence,

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792
