Which equation is equivalent to ( y = x^2 + 24x - 18 )?

• ( y = (x + 12)^2 - 162 )

• ( y = (x + 12)^2 + 126 )

• ( y = (x - 12)^2 - 162 )

• ( y = (x - 12)^2 + 126 )

Which equation is equivalent to
y = x² + 12x - 2?

• f(x) = (x + 6)² + 142

• f(x) = (x + 6)² - 34

• f(x) = (x + 6)² - 38

• f(x) = (x + 6)² + 34

Which of the following is an equivalent equation?

• y=-(x+5)² + 21

• y=-(x+10)² + 21

• y=-(x-10)² + 21

Which of the following represents a quadratic function?

What do you do to the 'b' value to correctly complete the square?

• square it and then add the result to both sides

• divide by it 2, square the result, then add the result to both sides

• divide it by 2, take the square root of it and then add the result to both sides

• only divide it by 2 and add the result to both sides
