I have the answers but need help solving step by step

13.   Write a quadratic equation that will have a solution of only x = 0. Note: this means there will be a double solution of x = 0.
 
y = x^2
 
14.   Write a quadratic equation that cannot be factored.
 
y = x^2 + 1
 
15.   The product of two consecutive positive integers is 72. Find the integers.

Answer:

Explanations are below

Step-by-step explanation:

13) If you want only the solution x = 0, an equation that works is y = x^2 because it only touches the x-axis at 0.

14) The equation y = x^2 + 1 doesn't factor, so this answer works.

15) Two consecutive positive integers that multiply to 72 would be 8 and 9. This is because 8 and 9 are consecutive, or next to each other, and they multiply to get 72.
