If α and β are the zeroes of the polynomial 2x2 + 3x – 7, then find a polynomial whose zeroes are and .
Answers
Answer:
Step-by-step explanation:
Since we cannot factor the expression, we must use quadratic formula:
Plug in a for 2, b for 3, and c for -7 and you should find your roots.

Area of the rectangle is determined by Binomial Multiplication as given below.
What is Binomial Multiplication ?
Binomial Multiplication follows FOIL method , Firsts , Outer terms , Inner Terms , Last Terms.
A rectangle is given and area of the rectangle has to be determined by splitting it into smaller rectangles.
Let the rectangle is of 5*3 ft
To determine the area the rectangle has been split into rectangles of 15 rectangles as seen in the figure attached.
Area of the smaller rectangle is given by Length * Breadth = 1*1
Let us consider x = 1
Then
The side of the rectangle will be ( x+4) ( x+2)
On solving this by FOIL
x² + 6x +8
Area = x² + 6x +8
Area = 1 + 6 + 8 = 15 sq.ft
Area of the bigger rectangle =
= ( Area of 1st rectangle + Area of 2nd Rectangle + ...... + Area of 15th Rectangle)
= 15 * ( Area of the smaller rectangle)
Area of the bigger rectangle = 15 * ( 1 * 1)

I have a rectangle that has an area of 4ft^2
I can split up that rectangle to smaller rectangles of 1ft^2
Then I can count how many smaller rectangles I have and deduce the area of the larger rectangle form that -> 1ft^2 * 4 = 4ft^2

The area of the circular ring of the fountain with a radius of 9 feet is approximately 254.34 square feet.
To find the area of the ring, we need to subtract the area of the smaller circle from the area of the larger circle. The area of a circle is given by the formula A = πr^2, where r is the radius of the circle. Therefore, the area of the larger circle is π(9^2) = 81π square feet, and the area of the smaller circle is π((9/2)^2) = 20.25π square feet.
Subtracting the area of the smaller circle from the area of the larger circle, we get:
81π - 20.25π = 60.75π
Using the approximation π ≈ 3.14, we get:
60.75π ≈ 60.75(3.14) ≈ 190.845
Therefore, the area of the ring is approximately 190.845 square feet, which is closest to option (d) 254.34 square feet.
