y=x^2-6x-10

Question

More help please 

Answer 1

y = x² - 6x - 10 is in the form Ax² + Bx + C = 0 , which is standard form

 

You can use the Quadratic Equation to solve for this.

 

Or you can complete the square.

 

y = x² - 6x + 9 - 9 - 10 = 0

 

(x - 3)² - 19 = 0

 

(x - 3)² = 19

 

x - 3 = √19

 

and 

 

x - 3 = -√19

 

x = 3 + √19 and 3 - √19 are the roots of this equation
