how to solve quadratic equations without b?
6422
Answer and Explanation: When a quadratic equation, ax2 + bx + c = 0, has no b term, then it has the form ax2 + c = 0. When this is the case, we can solve this equation...

Biquadratic equations. A biquadratic equation is a 4-degree equation without the terms of degree 1 and 3. To solve a biquadratic equation you have to do a change of variable: z = x2. Then you have to solve the quadratic equation and finally undo the change.

You should know that a quadratic equation looks something like this: x^2-3x+2=0 or ax^2+bx+c=0. This will be important later on. The first step is to press the program button on your calculator. Press the right arrow twice to get to new and select create new.

Step 1: To use the quadratic formula, the equation must be equal to zero, so move the –4x back to the left hand side. Step 2: Identify a, b, and c and plug them into the quadratic formula. In this case a = 3, b = 4, and c = 8. Step 3: Use the order of operations to simplify the quadratic formula.

The quadratic formula helps us solve any quadratic equation. First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√(b²-4ac))/(2a) . See examples of using the formula to solve a variety of equations.

For a quadratic equation ax2+bx+c = 0, the sum of its roots = –b/a and the product of its roots = c/a. A quadratic equation may be expressed as a product of two binomials.

To solve, first add 4 to both sides of the equation. X^2–4+4=0+4. You then have x^2=4. Next, take the square root of both sides, which leaves x=2.

If the quadratic polynomial = 0, it forms a quadratic equation. Therefore, the standard form of a quadratic equation can be written as: ax2 + bx + c = 0 ; where x is an unknown variable, and a, b, c are constants with 'a' ≠ 0 (if a = 0, then it becomes a linear equation).

Here are examples of other forms of quadratic equations: x(x - 2) = 4 [upon multiplying and moving the 4 becomes x² - 2x - 4 = 0] ... 3x(x + 8) = -2 [upon multiplying and moving the -2 becomes 3x² + 24x + 2 = 0] 5x² = 9 - x [moving the 9 and -x to the other side becomes 5x² + x - 9]
