What number is used to complete the square for the equation {eq}x^2 = 20x {/eq}? a) 100 b) 10 c) -10 d) -100 Complete A Square: Completing a square is a process where we take a standard form equation, e.g. {eq}y = ax2 + bx + c {...
ETo solve an equation by completing the square, manipulate it algebraically so that one side (in this case, the left side) is a perfect square trinomial and the other side (the right side) is a constant. Recall that a perfect square trinomial is a trinomial that can be factored as (ax...
By Vieta’s Formula,a is the sum of the integral zeros of the function, and so a is integral. Because the zeros are integral, the discriminant of the function, a2−8a, is a perfect square, say k2. Then adding 16 to both sides and completing the square yields (a−4)2=k2+1...
Perfect Squares: Completing the Square A perfect square is a polynomial which can be factored into a product of two terms that are equivalent using the formula {eq}(a \pm b)^2 = a^2 \pm 2ab + b^2 {/eq}. When we wish to complete the square, we need ...
Major renovations: When you make significant changes or improvements to a property — for example, fixing up a home that had been condemned, or completing an addition — you’ll likely need to obtain a certificate of occupancy before you can sell it. That’s in addition to needing a ...
No, merchant compliance is not determined or enforced by the government. And, while the PCI Security Standards Council manages security standards and looks for ways to improve security, it doesn’t enforce compliance either. Instead, the steps a business must take to be PCI compliant are in the...
Refactor this by completing the square to get (a2−54)2−1, which has a minimum value of −1. The answer is thus 2019−1=2018. Similar to Solution 1, grouping the first and last terms and the middle terms, we get (x2+5x+4)(x2+5x+6)+2019 . Letting y=x2+5x...
Refactor this by completing the square to get (a^2-5/4)^2-1, which has a minimum value of -1. The answer is thus 2019-1=2018.Similar to Solution 1, grouping the first and last terms and the middle terms, we get (x^2+5x+4)(x^2+5x+6)+2019 .Letting y=x^2+5x, ...
