The polynomial (2x-1)(x2 -2) - x(x2-x-2) can be written in the form ax3+bx2+cx + d where a, b, c, and d are constants. Find the value of a, b, c, and d.

Part B
Find the value of x. The area of the rectangle below is 170 square meters.

the answer is a beach is the best place to be

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
