The zeros of the function will be when f(x) = 0.
As 0 = 3x^2 - 7x + 1, you can use the quadratic formula to solve, finding that x = (7 + sqrt(37))/2 or (7 - sqrt(37))/2.
X = -3
Solution:
Distribute
6(x)+(6)(-1)+-x=-21
Combine
(6x+-x) + (-6) = -21
5x + -6 = -21
5x - 6 = -21
Add 6 to both sides
5x -6 + 6 = -21 +6
5x = -15
Divide both sides by 5
5x/5 = -15/5
x = -3

Answer:
Sue should buy 1.6 quart of paint.
Step-by-step explanation:
First we need to find out the area of longest wall
Area =length × breadth
Area= 10 × 8 = 80 square feet
To cover 50 square feet we have required 1 quart of paint
So for covering 1 square feet we have required 1/50 quart of paint
So for covering 80 square feet we have required ( 1×80 ) / 50 quart
= 1.6 quart of paint
