Form the perfect square trinomial in the process of completing the square. what is the value of c? x2 + 3x + c =7/4 + c

The value of c that forms a perfect trinomial is 9/4.

Polynomial is an expression that involves only the operations of addition, subtraction, multiplication of variables.

A trinomial has only three terms. A perfect square trinomial is a trinomial that can be written as the square of a binomial.

Given:

x² + 3x = 7/4

Add to both sides the square of half of the coefficient of x (9/4):

x² + 3x + 9/4 = 7/4 + 9/4

(x + 3/2)² = 4

The value of c that forms a perfect trinomial is 9/4.

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
