What is the discriminant of 3x^2 + 2x +1 = 0?

Discriminant: b² - 4ac = - 8 (no real solutions)

Step-by-step explanation:

We are given the following quadratic equation, 3x² + 2x + 1 = 0, where a = 3, b = 2, and c = 1.

In the Quadratic Formula, , the expression under the radical symbol, "b² - 4ac" is the discriminant, which tells us the number of solutions of a given quadratic equation.  When we substitute the values for a, b, and c of a given quadratic equation into the quadratic formula, we are essentially solving for its number of solutions.

Given the quadratic equation, 3x² + 2x + 1 = 0, where a = 3, b = 2, and c = 1, let us substitute the values for a, b, and c into the discriminant to determine its number of solutions:

Discriminant:  b² - 4ac =  (2)² - 4(3)( 1 ) = 4 - 12 = - 8

Hence, the discriminant of 3x² + 2x + 1 = 0 is -8, which means that the given quadratic equation has no real solutions.  This implies that the 3x² + 2x + 1 = 0 has no x-intercepts (because the graph does not cross the x-axis).  

Attached is a screenshot of the graphed quadratic equation, 3x² + 2x + 1 = 0, where it shows that it does not cross the x-axis, proving that there are no real solutions.

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
