Answer:
-3x⁴ - 9x³ + 15x² = -3x² (x² + 3x -5)
10x³ -35x² + 6x - 21 = (2x - 7) (5x² + 3)
Step-by-step explanation:
-3x⁴ - 9x³ + 15x² = -3x² (x² + 3x -5)
10x³ -35x² + 6x - 21 = (2x - 7) (5x² + 3)
If you solve for the vertex of the function, you would get (-3, -1). So I think it would be x = -3 and the function’s maximum value would be -1. Hope this helps!! :)
Given:
Faiz's total online shipping bill comes to £45.71.
He then receives discount of £15.90.
To find:
How much does he have to finally pay after the discount?
Solution:
We have,
Amount of bill = £45.71
Discount amount = £15.90
Now,
Final payment = Amount of bill - Discount amount
= £45.71 - £15.90
= £29.81
Therefore, Faiz's have tp pay £29.81 after discount.
