One latest school question and answer requested students to claim what they believe is the most crucial important aspect for a student to do in order for you to become success. The one which response stood out from the rest was practice. Persons who are definitely successful do not become successful by being born. They work hard and dedication their lives to succeeding. If you would like to attain your goals, keep this in mind! shown below some question and answer examples that you could potentially use to elevate your knowledge and gain insight that will guide you to maintain your school studies.
Question:
Which equation has the solutions mc012-1.jpg? 2×2 + 6x + 9 = 0 x2 + 3x + 12 = 0 x2 + 3x + 3 = 0 2×2 + 6x + 3 = 0
Answer:
The solutions are not displayed properly, therefore, I cannot provide an exact answer.
However, I will help you get the solutions for each of the given equations and then you can pick your correct one.
The general form of the quadratic equation is:
ax² + bx + c = 0
The solutions of a quadratic equation can be calculated using the quadratic formula shown in the attached image.
For the first choice:
2x² + 6x + 9 = 0
comparing this equation with the general formula, we will find that:
a = 2
b = 6
c = 9
Substituting with the values of a,b and c in the quadratic formula, we will find that that the solutions of this equation are and
For the second choice:
x² + 3x + 12 = 0
comparing this equation with the general formula, we will find that:
a = 1
b = 3
c = 12
Substituting with the values of a,b and c in the quadratic formula, we will find that that the solutions of this equation are and
For the third choice:
x² + 3x + 3 = 0
comparing this equation with the general formula, we will find that:
a = 1
b = 3
c = 3
Substituting with the values of a,b and c in the quadratic formula, we will find that that the solutions of this equation are and
For the fourth choice:
2x² + 6x + 3 = 0
comparing this equation with the general formula, we will find that:
a = 2
b = 6
c = 3
Substituting with the values of a,b and c in the quadratic formula, we will find that that the solutions of this equation are and
Hope this helps 🙂
They can easily hopefully guide the student resolve the question by applying the questions and answer examples. You might possibly then have a discussion with your classmate and continue the school learning by studying the topic as a group.
