How do you solve an equation like:
2x² = 10x - Correct Answer-FIRST - move everything to the left
2x² - 10x = 0
SECOND - factor GCF
2x (x -5) = 0

2x = 0 and x - 5 = 0
x = 0 and x = 5
When substituting numbers or variables, what should you do? - Correct Answer-put
them in parentheses
EX if b = 2x + 3, then b² = - Correct Answer-EX if b = 2x + 3, then
b² = (2x+3)(2x+3)= 4x² + 6x + 6x + 9
b² = 4x² + 12x + 9
1/2 * 32 is the same as... - Correct Answer-1/2 * 32 is the same as...
dividing 32 by 2
What can you take the square root of
√(x² +y²) OR √(x²y²)? - Correct Answer-We can only take the square root of √(x²y²) and
