Yes, this can be done this way:
(x-(-5))(x+a)=0, where a is any (positive or negative) number
This simplifies to: (x+5)(x+a) = 0
or written as quadratic: x2+(a+5)x+5a = 0
Solutions: x1 = -5 and x2 = -a,
so if a=5 the equation shortens to (x+5)2=0 ( or x2+10x+25=0 )
and there will be only one solution: x1,2 = -5

What do you do if the second difference in a quadratic equation is 1?
The second difference of a quadratic equation being one indicates the second derivative at that point is positive. What you do from there depends on what property or transformation you're looking for with respect to the equation.
Solve quadratic equation by using formulae?
with the quadratic equation being ax2+bx+c and the formula being x=[-b±(b2-4ac)1/2]/2a just plug in the values for a b and c the quantity raised to the one half denotes a square root of that quantity.
What is the general solution of a differential equation?
It is the solution of a differential equation without there being any restrictions on the variables (No boundary conditions are given). Presence of arbitrary constants indicates a general solution, the number of arbitrary constants depending on the order of the differential equation.
What is the value of the discriminant for the quadratic equation d2-7d plus 8 equals 0?
b2 - 4ac72 - 4(1)(8)49 - 32= 17---------this tells us, by being positive, that there are two real roots in this quadratic .
What is different between parabola and quadric equation?
There is no such thing as a quadric equation. The nearest word is quartic which is an equation involving the fourth power of the independent variable. It is unlikely that you will have come across that. It is possible that you might be wanting to refer to a quadratic equation, which is the equation of a parabola. That being the case, they two represent the same thing.
Is there a solution to the quadratic equation of 3x squared -10x equals -5?
Yes because rearranging it into the form of 3x2-10x+5 = 0 makes the discriminant of the quadratic equation greater than zero which means it will have two different solutions. Solving the equation by means of the quadratic formula gives x as being 2.721 or 0.613 both corrected to 3 decimal places.

When can you say that a number is called a solution in algebraic expression?
An algebraic equation or inequality can have a solution, an algebraic expression cannot. If substituting a number in place of a variable results in the equation or inequality being a true statement, then that number is a solution of the equation or inequality.

How aerospace engineers use the quadratic equation?
The quadratic equation is used to find the intercepts of a function (F(x)=x^(2*n), n being an even number) along its primary axis (typically the x axis). Many equations follow this form. The information given by the quadratic equation depends on what your function is pertaining to. If say you have a velocity vs time graph, when the function crosses the xaxis your particle has changed from a positive velocity to a negative velocity. This information can be useful to determine the accompanying behavior of your position. The quadratic equation is simply a tool to find intercepts of a function.

What Albert Einstein create?
Albert Einstein Created the equation for gravity being e=mc2.
How many sides does an irregular polygon have if it has 252 diagonals showing work?
Let its sides be x and rearrange the diagonal formula into a quadratic equation:- So: 0.5(x^2-3x) = 252 Then: x^2-3n-504 = 0 Solving the quadratic equation: gives x a positive value of 24 Therefore the polygon has 24 sides irrespective of it being irregular or regular
What does solving a quadratic equation tell you?
It tells you what values of x give a result of zero. Graphically, they represent the x-intercepts. It might tell you after how many seconds a ball hits the ground after being thrown in the air.
