How do you factor an equation with a squared number in it. Example 5 minus 8x plus 3 times x squared?

5 - 8x + 3x2
= 3x2 - 8x + 5 (since the sign of the second term is negative, then 5 can be factored as (-1)(-5))
= (3x - )(x - ) (try to put 1 or 5 to the empty places, in order to obtain -8x)
= (3x - 5)(x - 1)

What is an example of a factor?
A factor is a number that divides evenly into another number with no remainder. 3 is a factor of 9. 4 is not a factor of 9.
Are there prime numbers that are also square mumbers?
No. That isn't possible: A prime number, by definition, has no smaller factors. A square number does have a smaller factor - the number that is squared.
What is one factor of 16?
Here are some factors of 16:1,2,4,8,16.A factor of a number is a number that when you multiply it with a number it will equal the other number for example 1 is a factor of 16 because 16x1=16.
What happens to the greatest common factor of the cylinders' surface area if its radius is squared?
Nothing. The cylinder's surface area does not have a GCF.
What is a factor give an example?
a number or algebraic expression by which another is exactly divisible. 3 is a factor of 9
What is an equation that performs mathematical calculations on number values?
A squared plus b squared equils c squared
Is 4 a squared number and a factor of 60?
Yes.
What is an example of a two squared number is another squared number?
9 + 16 = 25
The product of a number squared and 8 as an equation?
(y^2)x8
What is decay factor?
The constant factor that each value in an exponential decay pattern is multiplied by the next value. The decay factor is the base in an exponential decay equation. for example, in the equation A= 64(0.5^n), where A is he area of a ballot and the n is the number of cuts, the decay factor is 0.5.
How do you define the square root?
A square root is the factor of a number once squared. for example √100 is 10. 10 x 10 or 102= 100.
What does squared mean in maths?
Squared means: So basically, say a number, for example 6, it would be 6x6. Another example, a number like 3, 3 squared would be 3x3. It means that A number times that number you just said.
How much is squared?
The number times itself. For example 2 squared = 2x2=4 so 2 squared =4
How do you factor out square roots?
To factor a square root you must divide a specific number by another number that is a factor of the specific number. The factor of the specific must also be able to be multiplied by itself to equal the specific number. x multiplied by x equals y. For example: The square root of 144 would be 12 because 12 squared (multiplied by itself) is 144.
What a squared number?
The result of a number multiplied by itself
How do you factor the expression x squared minus x squared minus?
Without that other number, all you've got is zero.
Factor x squared plus x minus 10?
to factor this equation you need to use the quadratic formula:in this question a=1, b=1, c= -10so after you plug in those number you answer would be:x= (-1+ or - the square root of -39) divided by 2
