Answer:
1) 1 2)100 3)6.25.
Step-by-step explanation:
Any trinomial is of the form ax^2+bx+c .
To make the expression a perfect square we take half of b term then square it Add This is what we add to make the expression a perfect square.
1)Half of coefficient of x term is 1 .
Square it that is 1 is added to make it a perfect square.
2) Half of coefficient of x term that is 20÷2=10 .Square it that is 100 is added to make it a perfect square.
3) Half of coefficient of x that is 5÷2=2.5.Square it 6.25 is added to the expression to make it a perfect sqauare.
