How do you find the minimum point of an equation?

If your quadratic equation has a positive a term, it will also have a minimum value. You can find this minimum value by graphing the function or by using one of the two equations. If you have the equation in the form of y = ax^2 + bx + c, then you can find the minimum value using the equation min = c – b^2/4a.

How many solutions does X² =- 16 have?

two solutions
If we have the equation x2 = 16, what are the solutions to the equation? Since the square of a positive or negative number are always positive, this equation has two solutions, namely x = -4 or x = 4.

What is the best method to be used in solving quadratic equation x2 16x 63 0?

3.2 Solving x2-16x+63 = 0 by Completing The Square .

What are the roots of the equation x2 16?

Step-by-step explanation: x = (-4) and x = 4 are solution of the equation x² = 16.

What is the completely factored form of x2 16?

Explanation: There are two ways to factorize x2−16 – one using identity a2−b2=(a+b)(a−b) . Other method is by splitting the middle term, which is 0 here and as product of coefficient of x2 and constant term is −16 . we need to do is to split middle term in 4 and −4 (as their sum is zero and product is −16 ).

What is the best method to be used in solving quadratic equation x2 5x 8 0?

Solve Quadratic Equation by Completing The Square 2.2 Solving x2+5x-8 = 0 by Completing The Square .

What is the best method to be used in solving quadratic equation?

Quadratic formula – is the method that is used most often for solving a quadratic equation. If you are using factoring or the quadratic formula, make sure that the equation is in standard form.

What is the formula for Factor X ^ 2-16?

Algebra. Factor x^2-16. x2 − 16 x 2 – 16. Rewrite 16 16 as 42 4 2. x2 − 42 x 2 – 4 2. Since both terms are perfect squares, factor using the difference of squares formula, a2 −b2 = (a+b)(a−b) a 2 – b 2 = ( a + b) ( a – b) where a = x a = x and b = 4 b = 4.

Which is the local minimum of a stationary point?

We can see quite clearly that the stationary point at (− 2, 21) is a local maximum and the stationary point at (1, − 6) is a local minimum . Given the function defined by: y = x3 − 6×2 + 12x − 12 Find the coordinates of any stationary point (s) along this function’s curve’s length. Step 1: find dy dx. Step 2: solve the equation dy dx = 0.

Is the curve y = x2 a stationary point?

We can therefore state that the curve y = x2 − 4x + 5 has one stationary point with coordinates (2, 1) . This result is confirmed, using our graphical calculator and looking at the curve y = x2 − 4x + 5 : We can see quite clearly that the curve has a global minimum point, which is a stationary point, at (2, 1) .
