Answer:
<em>64 ; 8</em>
Step-by-step explanation:
a² ± 2ab + b² = (a ± b)²
x² + 2(8)(x) + 8² =
x² + 16x + <em>64</em> =
(x + <em>8</em>)²
<span>1800 = -3p^2+70p+988
0 = -3p^2+70p - 812
Using the discriminant means taking the section of the quadratic formula:
âšâ€‹(b^2)â’4ac
And by plugging in the values of our formula we get:
âšâ€‹(70^2)â’4*-3*-812
Which yields:
âšâ€‹4900 â’ 9744
Since this is a square root of a negative number, it says there is no real solution for the formula, which makes sense because the formula is a quadratic that is pointing downwards (a = -3p^2) and underneath the number line (c = -812).

Answer:
7y
Step-by-step explanation:
7yg^0 is equal to 7y(1). Anything to the power of 0 is equal to 1. This means that the expression will be equal to 7y times 1 or 7y.
