3 hours ago Check if x (x + 1) + 8 = (x + 2) (x – 2) is in the form of** quadratic equation.** Solution: Given, x (x + 1) + 8 = (x + 2) (x – 2) x 2 +x+8 = x 2 -2 2 [By algebraic identities] Cancel x 2 both the sides. x+8=-4. x+12=0. Since, this expression is not in the form of ax 2 +bx+c, hence it is not a** quadratic equation.** 3.

8 hours ago Answer: The** quadratic equation formula** is: x= {-b +/- (b²-4ac)¹/² }/2a. The determinant or b²-4ac = (-5)² - 4 × 3 × 2 = 25 - 24 = 1. or, (b² - 4ac)¹/² = 1. Therefore, x = { - (-5) + 1}/2 × 2= 6/4 = 3/2. or, x = {- (-5) - 1}/2 × 2 = 4/4 = 1. Thus the roots of the** equation** are 3/2 and 1.

The **Quadratic** **Formula**: For ax2 + bx + c = 0, the values of x which are the solutions of the equation are given by: For the **Quadratic** **Formula** to work, you must have your equation arranged in the form "(**quadratic**) = 0". Also, the "2a" in the denominator of the **Formula** is underneath everything above, not just the square root.

- Write the equation in the form of: ax2 +bx +c = 0 a x 2 + b x + c = 0
- Factorize the quadratic and solve for the variable.
- Use quadratic formula if you couldn’t factorize the quadratic.
- Quadratic formula: x = −b± b2−4ac√ 2a x = − b ± b 2 − 4 a c 2 a

The quadratic formula is a technique that can be used to solve quadratics, but in order to solve a quadratic using the quadratic formula the problem must be in the correct form. To solve a quadratic using the quadratic formula the quadratic must be in the form **ax2 + bx + c = 0**.

The quadratic equation is used in the design of almost every product in stores today. The equation is used to determine how safe products are and the **life expectancy of products**, such as when they can expect to quit working. Designers can then see what needs to be changed in the product to make it last longer.
