Solution of a quadratic equation represented as is given as:
Comparing the given equation with standard equation:
a = 1
b = 3
c = 4
So, the roots are:
can be written as
and
So,
The numbers containing in them, are called as complex numbers.
Therefore, the roots of the equation can be written as:
The width of the mattress is 7.
Give that
- The area of the mattress is 56 square feet.
- The length is 8.
- And, the width of the bed is x + 4.
Now as we know that
Area of the rectangle = Length × width
56 square feet = 8 × (x + 4)
56 = 8x + 32
56 - 32 = 8x
x = 3
So, the width is
= 3 + 4
= 7
Therefore we can conclude that the the width of the mattress is 7.
