Which value must be added to the expression x2 – 3x to make it a perfect-square trinomial?
3/2
9/4
6
9

The value that must be added to the expression to make it a perfect square is (b) 9/4

The expression is given as:

Represent the coefficient of x with k.

So, we have:

Divide both sides of the equation by 2

Take the square of both sides

Evaluate the squares

Hence, the value that must be added to the expression to make it a perfect square is (b) 9/4

Step-by-step explanation:

Given

x² - 3x

To make the expression a perfect square

add ( half the coefficient of the x- term )²

x² + 2( - )x + , thus

x² - 3x +

= (x - )² ← a perfect square

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
