The zeroes (also called the x-intercepts) are found in standard form by using a formula called the quadratic formula. The quadratic formula looks like this:
This is an example of a question that asks you to find the x-intercepts from standard form: Use the quadratic formula to solve the following question 0=5x^2-7x+2 You would just sub in the values to the quadratic formula b=-7 a=5 c=2
