Which of the following constants can be added to x2 - 3x to form a perfect square trinomial?
3/4
1 1/2
2 1/4

ANSWER

EXPLANATION

We want to find the constant that must be added to

to form a perfect square.

Comparing the given expression to

we have

a=1 , b=-3 , and c=0.

We need to add

We substitute the values to get,

We change this to mix numbers to get,

The last choice is correct.

“a term can be a signed number, a variable, or a constant multiplied by a + sign or j sign. in , the terms are 5x , 3y and 8. when a term is made up of a constant multiplied by a variable or variables, that constant is called a coefficient.” i hope this you.
