(x - 5i√2)(x +5i√2)
given the roots of a polynomial p(x), say x = a and x = b
then the factors are (x - a)(x - b)
and p(x) is the product of the factors ⇒ p(x) = (x - a)(x - b)
here x² + 50 = 0 ⇒ x² = - 50 → ( set = 0 for roots)
take the square root of both sides
x = ± √-50 = ± √(25 × 2 × -1) = √25 × √2 × √-1 = ± 5i√2
The roots are x = ± 5i√2
thus the factors are ( x - ( - 5i√2)) and (x - (+5i√2))
x² + 50 = (x + 5i√2)(x - 5i√2)
I would say to add the 2 prices together and that would be your answer!
So your answer is 261.81!
Hope this helps!
Answer:
The circumference and the area of the circle are 6.28 yards and 3.14 yd² respectively.
Step-by-step explanation:
Circumference: This is defined as the distance around a circle.
The circumference of a circle is
P = πd............................. Equation 1
Where p = circumference of the circle, d = diameter of the circle
Area: This is the region bounded by a plane surface.
The area of a circle is
A = πd²/4 .................................. Equation 2
Where A = area of the circle, π = pie = constant.
Given: d = 2 yd.
Constant: π = 3.14
Substituting these values into equation 1 and 2 respectively.
P = 3.14(2)
P = 6.28 yard.
P = 6.28 yd
and
A = 3.14(2)²/4
A = 3.14×4/4
A = 3.14 yd²
Thus the circumference and the area of the circle are 6.28 yards and 3.14 yd² respectively.
