What is the difference between factoring and solving?
The difference between factoring and solving is...Factoring: The answer would be in multiplication form.Example: x²+7x+12=0 is the same as (x+3)(x+4)Solving: The answer would be what the unknown variable is equal too.Example: x²+7x+12=0 is the same as x=-3 or X=-4
Find the value of 2 numbers if their sum is 12 and their difference is 4?
x+y=12 x-y =4 x=12-4 =8 8+y=12 y=12-8 =4 so x=8 y=4 8+4=12 8-4=4
How would the expression x cubed minus 8 be rewritten using the difference of cubes?
Answer: (x - 2)(x² + 2x + 4)Factor the difference of cubes:a³ - b³ = (a - b)(a² + ab + b² )note 8 = 2³ = 8 ⇒ b = 2 , with a = xSox³ - 8= x³ - 2³= (x - 2)(x² + 2x + 2²) = (x - 2)(x² + 2x + 4)
How do you do exponents?
Instead of writing 4 x 4 x 4 = 64 you can write it in exponent form, thus: 43 and get the same answer of 64 If you see 54 it is the same as 5 x 5 x 5 x 5 = 625 (Don't assume that 54 is 5 x 4 = 20 - big difference!)
How would you write the algebraic expression for one fourth the difference of a number and 7?
The algebraic expression for one fourth the difference of a number and 7 can be written as (1/4)(x - 7), where x represents the unknown number. This expression first calculates the difference between the number and 7 by subtracting 7 from the number (x - 7), then finds one fourth of that difference by multiplying the result by 1/4.
How do you factor x squared minus 16?
It is the difference of squares. (x-4) and (x+4) <--- answer
What two numbers LCM is 60 and the difference between the two numbers is 3?
1 x 60 difference 59 2 x 30 difference 28 3 x 20 difference 17 4 x 15 difference 11 5 x 12 difference 7 6 x 10 difference 4 Are you sure the question is correct?
What is a example of the difference of a square?
It is for example: x2-16 = (x-4)(x+4)
How do you write the difference between 3 times x and 4?
(3*x)+4
Is there a difference between 4x and x raised to the power of 4?
Yes. 4x means 4 multiplied by x. x4 means x multiplied by x multiplied by x multiplied by x.
How do you write 4 less than the cube of the difference of a different number and7?
Let X = the different number the difference is x-7 the cube of the difference is (x-7) to the 3rd power (x-7)^3 - 4 = y
What are the factors of x 2 - 16?
Assuming that is x squared minus 16: x2 - 16 = (x + 4)(x - 4) (The difference of two squares.)
What is the answer to 4 - x 4?
0
What are two factors of 52 with a difference of 9?
The factor pairs of 52 are: 1 x 52 2 x 26 4 x 13 with the last pair (4 and 13) having a difference of 9.
What is four more than the difference of two numbers?
If the two numbers are X and Y, it is |X - Y| + 4 or abs(X - Y) + 4
What is the mathematical symbol of twice the difference of x and 4 is greater than the reciprocal of 13?
2(x-4) > 1/13
What is the slope between the given points of -4 -1 and 4 5?
Calculate the difference of the y-coordinates, and divide it by the difference of the x-coordinates. That is the slope.
