Q. 3x2+2x=11Which of the following describes the solutions to the given equation?Choose 1 answer:(A) The equation has two distinct rational solutions.B The equation has two distinct irrational solutions.(C) The equation has one distinct real solution.D The equation has no real solutions.
Rewriting the equation: First, we need to rewrite the equation in standard form by moving all terms to one side of the equation. 3x2+2x−11=0
Determining factorability: Next, we will determine whether the quadratic equation can be factored easily. If not, we will use the quadratic formula to find the solutions.The quadratic formula is given by x=2a−b±b2−4ac, where a, b, and c are the coefficients from the quadratic equation ax2+bx+c=0.
Identifying coefficients: Let's identify the coefficients a, b, and c from our equation.a=3, b=2, and c=−11.
Calculating the discriminant: Now, we will calculate the discriminant, which is the part under the square root in the quadratic formula: b2−4ac. Discriminant = (2)2−4(3)(−11)=4+132=136.
Determining the number of solutions: Since the discriminant is positive (136 > 0), we know that there are two distinct real solutions.Now we need to determine if these solutions are rational or irrational.
Determining the nature of solutions: The discriminant is not a perfect square, which means the solutions will involve the square root of a non-perfect square number. Therefore, the solutions are irrational.
Concluding the solutions: Given that the discriminant is positive and not a perfect square, we can conclude that the equation has two distinct irrational solutions.
