Q & A
What is a rational equation?
-A rational equation is an equation that involves fractions whose numerators and/or denominators are polynomials.
How can you solve the equation โ(x + 2) = 4?
-To solve the equation โ(x + 2) = 4, square both sides to eliminate the square root, resulting in x + 2 = 16. Then solve for x by subtracting 2 from both sides, giving x = 14.
What is an exponential equation?
-An exponential equation is an equation where the variable appears in the exponent. For example, 7^x - 3^x = 1.
What is the highest degree of a polynomial?
-The highest degree of a polynomial is the greatest exponent of its variable. For example, in the polynomial 3x^3 - 9x^2 + 9, the highest degree is 3.
How do you identify a quadratic equation?
-A quadratic equation is of the form ax^2 + bx + c = 0, where a, b, and c are real numbers and a โ 0.
What is the standard form of a quadratic equation?
-The standard form of a quadratic equation is ax^2 + bx + c = 0.
What is an example of a quadratic equation?
-An example of a quadratic equation is 2x^2 + 5x - 3 = 0.
What distinguishes a linear equation from a quadratic equation?
-A linear equation has a highest degree of 1, such as 5a - 9 = 19, whereas a quadratic equation has a highest degree of 2, such as 2x^2 + 5x - 3 = 0.
Why is the equation 1/(2x^2 - 1) = 8 not considered a quadratic equation?
-The equation 1/(2x^2 - 1) = 8 is not considered a quadratic equation because it is a rational equation, not a polynomial.
How do you transform the equation 3x(x - 2) = 10 into standard quadratic form?
-To transform 3x(x - 2) = 10 into standard quadratic form, expand and rearrange it: 3x^2 - 6x = 10 becomes 3x^2 - 6x - 10 = 0.
