Find the vertex of y = x2 + 14x − 40 by completing the square. a. (−7, 89) b. (−89, −7) c. (7, 89) d. (−7, −89)

Alright, lets get started.

For making complete square, we will add and subtract 49 in this

Comparing the standard equation of parabola

where (h,k) are vertex

So, comparing the equation with standard one, h, k would be = (-7 , -89)

So, the vertex are (-7 , -89) : Answer

Hope it will help :)
