Factor:5x^2 + 6x + 1
The answer is: (x + 1)(5x + 1)
200
What formula (m * n) is this matrix? [2 5 6]
The matrix is a 1 * 1 -The reason why is because there is one row across & one row down.
200
Solve for x: x+35+283= 354
x = 36
200
What do you do when you try to add radicals without the same base?
You just add the numbers in front of the radicals OR you can check to see if one of the radicals can be simplified.
200
What is an equation?
A written statement indicating the equality of two expressions. It consists of a sequence of symbols that is split into left and right sides joined by an equal sign.

x = 35
300
Are radicals and square roots the same thing?
Yes
300
What is the definition of factoring?
To factor a number means to break it up into numbers that can be multiplied together to get the original number.
400
Factor: 8x^2 - 10x + 3
The answer is: (4x - 3)(2x - 1)

What is the definition of matrices (matrix)?
A matrix is a rectangular array of numbers. The size of a matrix is defined by the number of rows and columns that it contains. A matrix with m rows and n columns is called an m × n matrix or m-by-n matrix, while m and n are called its dimensions.
