Given:
The function, f(x) = -2x^2 + x + 5
Quadratic equation: 0 = -2x^2 + x +5
where a = -2
b = 1
c = 5
The discriminate b^2 - 4ac = 41
To solve for the zeros of the quadratic function, use this formula:
x = ( -b +-√ (b^2 - 4ac) ) / 2a
x = ( 1 + √41 ) / 4 or 1.85
x = ( 1 - √41 ) / 4 or -1.35
Therefore, the zeros of the quadratic equation are 1.85 and -1.35.
(1,5)
To find this, do the opposite of how you got to (4,5).
Move right 2 units instead of left.
Move left 5 units instead of right.
Now, your on the point (1,5).
To check this, do what they said. (Move left 2 units and right 5 units) If its correct you end up on (4,5)
