What is the x value for?
Value of x is used to consider unknown value. The letter “x” is commonly used in algebra to indicate an unknown value. It is referred to as a “variable” or, in some cases, a “unknown.” In x + 2 = 7, x is a variable.
How do you find the value of x in a quadratic equation?
The quadratic formula is: x=−b±√b2−4ac2a x = − b ± b 2 − 4 a c 2 a , where a and b are the coefficients of the x2 and x terms, respectively, in a quadratic equation, and c is the value of the equation’s constant.
What is the value of C in the quadratic equation?
-1
Graphs of Parabolas The c-value is where the graph intersects the y-axis. In this graph, the c-value is -1, and its vertex is the highest point on the graph known as a maximum. The graph of a parabola that opens up looks like this. The c-value is where the graph intersects the y-axis.

How to find the solution of x2-6x-16?
To find equation solutions, solve x-8=0 and x+2=0. To find equation solutions, solve x − 8 = 0 and x + 2 = 0. x2-6x-16=0 Two solutions were found : x = 8 x = -2 Step by step solution : Step 1 :Trying to factor by splitting the middle term 1.1 Factoring x2-6x-16 The first term is, x2 its
What is x^2 — 16=0?
Since x^2 — 16=0 we can move 16 to the RHS that is the right hand side of the equation. This causes the sign of 16 to change. That is it will become +16 on RHS when it had been -16 on the LHS that is the left hand side.
How do you solve X2 + 16 = 0 using quadratic formula?
How do you solve x2 + 16 = 0 using the quadratic formula? The number under the square root is negative, so there are no real solutions.
What is the value of X in 4×4?
X^2=16 that is 16 is the square of x. This is a perfect root that is it has a whole number as its root. 4×4 that is 4^2 =16 so x=4 So x can also be -4 so the values of x can be 4 and -4.
