10x454x0.55=2,497 grams of fruit
A.
Find the dimensions of the original painting.
Since the scale is 1 in : 40 cm
2 in ( 40 cm / 1 in) = 80 cm
1.5 in ( 40 cm / 1 in) = 60 cm
80 cm by 60 cm
B.
Find the area of the original painting.
<span>A = 80
cm x 60 cm = 4800 sq cm</span>
C.
Since 1 inch is 2.54 cm, find the dimensions of the original painting in
inches.
80 cm ( 1 in / 2.54 cm) = 31.5 in
60 cm ( 1 in / 2.54 cm) = 23.6 in
D,
Find the area of the original painting in square inches.
A = 31.5 in x 23.6 in = 743.4 sq in

A factorization of

<h3>What are the properties of roots of a polynomial?</h3>
- The maximum number of roots of a polynomial of degree
is
. - For a polynomial with real coefficients, the roots can be real or complex.
- The complex roots of a polynomial with real coefficients always exist in a pair of conjugate numbers i.e., if
is a root, then
is also a root.
If the roots of the polynomial
are
, then it can be factorized as
.
Here, we are to find a factorization of
. Also, given that
and
are roots of the polynomial.
Since
is a polynomial with real coefficients, so each complex root exists in a pair of conjugates.
Hence,
and
are also roots of the given polynomial.
Thus, all the four roots of the polynomial
, are:
.
So, the polynomial
can be factorized as follows:
![\{x-(-2+i\sqrt{7})\}\{x-(-2-i\sqrt{7})\}\{x-(1-i\sqrt{3})\}\{x-(1+i\sqrt{3})\}\\=(x+2-i\sqrt{7})(x+2+i\sqrt{7})(x-1+i\sqrt{3})(x-1-i\sqrt{3})\\=\{(x+2)^2+7\}\{(x-1)^2+3\}\hspace{1cm} [\because (a+b)(a-b)=a^2-b^2]\\=(x^2+4x+4+7)(x^2-2x+1+3)\\=(x^2+4x+11)(x^2-2x+4)](https://tex.z-dn.net/?f=%5C%7Bx-%28-2%2Bi%5Csqrt%7B7%7D%29%5C%7D%5C%7Bx-%28-2-i%5Csqrt%7B7%7D%29%5C%7D%5C%7Bx-%281-i%5Csqrt%7B3%7D%29%5C%7D%5C%7Bx-%281%2Bi%5Csqrt%7B3%7D%29%5C%7D%5C%5C%3D%28x%2B2-i%5Csqrt%7B7%7D%29%28x%2B2%2Bi%5Csqrt%7B7%7D%29%28x-1%2Bi%5Csqrt%7B3%7D%29%28x-1-i%5Csqrt%7B3%7D%29%5C%5C%3D%5C%7B%28x%2B2%29%5E2%2B7%5C%7D%5C%7B%28x-1%29%5E2%2B3%5C%7D%5Chspace%7B1cm%7D%20%5B%5Cbecause%20%28a%2Bb%29%28a-b%29%3Da%5E2-b%5E2%5D%5C%5C%3D%28x%5E2%2B4x%2B4%2B7%29%28x%5E2-2x%2B1%2B3%29%5C%5C%3D%28x%5E2%2B4x%2B11%29%28x%5E2-2x%2B4%29)
Therefore, a factorization of
is
