Answer:
x⁴ + 2 x² + 1
Step-by-step explanation:
given solution of the polynomial
i, −i, 1, −1.
equation of the polynomial will be equal to
=(x - i)(x + i)(x - 1)(x + 1)
= (x² + i x - i x - i²)(x² + x - x + 1)
=(x² - (-1))(x² + 1 )
= (x² + 1)(x² + 1)
= x⁴ + x² + x² + 1
= x⁴ + 2 x² + 1
hence, the required polynomial equation is x⁴ + 2 x² + 1
Answer:
Step-by-step explanation:
We have been given the formula of area of a circle and we are asked to write the formula of diameter in terms of the area of the circle.
We will use substitution method to solve for d. From equation (2) we will get,
Upon substituting this value in equation (1) we will get,
Let us multiply both sides of our equation 4.
Let us divide both sides of our equation by pi.
Let us take square root of both sides of our equation.
Therefore, the equation represents the formula for diameter in terms of the area of the circle.
Step-by-step explanation:
Correction:
1⟩
Given equation is x²-3x = 4
⇛ x²-3x -4 = 0
⇛ x²+x-4x-4 = 0
⇛ x(x+1)-4(x+1) = 0
⇛ (x+1)(x-4) = 0
⇛ x+1 = 0 or x-4 = 0
⇛ x = -1 or x = 4
2.⟩
Given equation is x²+4x+4 = 0
⇛ x²+2x+2x+4 = 0
⇛ x(x+2)+2(x+2) = 0
⇛ (x+2)(x+2) = 0
⇛ x+2 = 0
⇛ x = -2
Well I can't see the picture clearly but what I can.n see is that you need f×2,360 and you also need to find what f is then go on from their
