Rewriting the equation as a quadratic equation equal to zero:
x^2 - x - 30 = 0
We need two numbers whose sum is -1 and whose product is -30. In this case, it would have to be 5 and -6. Therefore we can also write our equation in the factored form
(x + 5)(x - 6) = 0
Now we have a product of two expressions that is equal to zero, which means any x value that makes either (x + 5) or (x - 6) zero will make their product zero.
x + 5 = 0 => x = -5
x - 6 = 0 => x = 6
Therefore, our solutions are x = -5 and x = 6.
Answer:
68%
Step-by-step explanation:
85 divided by 125 = .68 * 100 = 68
original points (-2,0), (2,0), (0,2)
new points (-6.25,0),(6.25,0),(0,6.25)
the point (0,6.25) is the vertex that lies on y -axis
