Kim used 4 tulips in the bouquet.

Step-by-step explanation:

Tulips used = x

Daffodils used = x²

Total flowers in bouquet = 20

According to given statement;

[tex]x^2+x=20\\x^2+x-20=0[/tex]

Factorizing the Eqn

[tex]x^2+5x-4x-20=0\\x(x+5)-4(x+5)=0\\(x+5)(x-4)=0[/tex]

Either,

x+5=0        => x= -5

Or,

x-4=0        => x = 4

As the number of flowers cannot be negative, therefore,

x = 4 (Where x is the number of tulips used)

Kim used 4 tulips in the bouquet.
