Answer:
Solution is not correct.
Step-by-step explanation:
Given question is incomplete; Here is the complete question.
Is the solution shown in the attachment correct ?
9x + 2 = 8x² + 6x
We have to solve this equation with the help of quadratic formula,
-8x² + 9x + 2 = 6x
-8x² + 9x - 6x + 2 = 0
-8x² + 3x + 2 = 0
Quadratic formula of a standard quadratic equation (ax² + bx + c = 0) is,
x =
By comparing our equation with the standard quadratic equation,
a = -8
b = 3
c = 2
By substituting the values of a, b and c in the quadratic formula,
x =
x =
x =
Therefore, the given solution is not correct.
Each day <span>28800</span> acres are being destroyed per day
Solution by completing the square.
-5x^2+20x-17
=-5(x^2-4x)-17
=(-5(x-2)^2+20) -17
=-5(x-2)^2+3
So a=-5, d=-2, e=+3
a+d+e=-5-2+3=-4
