What is a Quadratic Equation?
- Quadratic equations are the polynomial equations of degree 2 in one variable of the type
where a, b, c, ∈ R and a ≠ 0. - The standard form of a quadratic equation is
.
Here, the given equation is (2x+7)(x-5) = - 43 + jx
On simplifying the equation we get,

By comparing the given equation with the standard form of the quadratic equation we get,
a = 2
b = - (3 + j)
c = 8
Therefore,

Take the square root of both sides,

3 + j = ±8
Therefore,
3 + j = 8
j = 8 - 3
j = 5
or
3 + j = -8
j = -8 - 3
j = -11
Hence, the possible values of 'j' are -11,5.

Answer:
<u>The total area of Tony's vegetable garden is 124 square feet</u>
Step-by-step explanation:
The total area of Tony's vegetable garden is composed by three rectangles.
1st rectangle
Length = 10 feet
Width = 6 feet (14 - 8)
Area = 6 * 10 = 60 square feet
2nd and 3rd rectangles are equals
Length = 4 feet
Width = 8 feet (14 - 6)
Area = 2 * 4 * 8 = 2 * 32 = 64 square feet
Total area
Area of the three rectangles
60 + 64 = 124 square feet
