Solving a quadratic using the square root method

The video tutorial explains how to find X and Y intercepts in equations, emphasizing that the Y value is zero at the X intercept. It demonstrates solving simple equations by isolating variables using inverse operations. The tutorial further explores the concept of square roots, highlighting the need to consider both positive and negative values when introducing square roots. The session concludes with a summary of key mathematical concepts covered.

What is the first step in finding the X-intercept of an equation?

• Add 25 to both sides

• Set Y equal to 0

• Subtract 25 from both sides

• Set X equal to 0

When solving the equation Y = X - 25, what operation should be performed to isolate X?

• Divide both sides by 25

• Multiply both sides by 25

• Subtract 25 from both sides

• Add 25 to both sides

What is the inverse operation of squaring a number?

• Square root

• Addition

• Subtraction

• Multiplication

When introducing the square root in an equation, what must be considered?

• Both positive and negative roots

• Only the positive root

• Only the negative root

• Neither root

In the equation 0 = X^2 - 25, what is the value of X after solving?

• X = ±5

• X = 25

• X = 0

• X = 5
