Answer:
-2x^2 +x -10
Step-by-step explanation:
-3x + xᶺ2 – 8 + 4x – 3xᶺ2 – 2
Combine like terms
x^2 - 3x^2 -3x+4x -8-2
-2x^2 +x -10
Answer:
x = - 1
Step-by-step explanation:
The equation of the axis of symmetry for a parabola in standard form
y = ax² + bx + c : a ≠ 0 is found using
x = -
y = - x² - 2x - 5 ← is in standard form
with a = - 1 and b = - 2, thus equation of axis of symmetry is
x = - = - 1
Equation of axis of symmetry is x = - 1
