The polynomial as per the given of the problem is f(x)=3x²-21x+30
Find the roots of this polynomial:
x₁=[-b+√b²-4ac)]/2a and x₂ =[-b-√b²-4ac)]/2a
Plug in : x₁ = [21+√(21²-4(3)(30)]/6 = [21+√81}/6 ; x₁ = 5
and x₂ = [21-√(21²-4(3)(30)]/6 = [21-√81]/6 ; x₂ = 2
Remark: I don't understand where did you bring √5 , it should be 5
Answer:
i have find the value of x and y in above figure hope it helps

Answer:
Option 1
Step-by-step explanation:
Answer:
$98.82
Step-by-step explanation:
Given data
A pair of shoes cost $52 and a dress was $70 at Belk
Total expenses
= 52+70
= $122
coupon = 25%
=25/100* 122
=0.25*122
= $30.5
Tax= 6%
= 6/100*122
= 0.06*122
= $7.32
Hence the total is
= 122-30.5+7.32
= 91.5+7.32
= $98.82
