Answer:
50° F
Step-by-step explanation:
To convert C° to F°, Multiply the celcius temperature by 9/5, then add 32 to it.
10 x 9/5 = 18
18 + 32 = 50
The resulting expression on factorization by grouping method is (3-7x²)(x-3).
<h3>What is Factorization?</h3>
Factorization is a method in which an Integer or an expression is written in terms of product of its fractions.
The expression given in the question is
–7x³ + 21x² + 3x – 9
This equation has to be factorized using grouping method.
group of two or more is formed and common term is taken out.
-7x² (x -3) +3(x-3)
( -7x²+3) (x-3)
(3-7x²)(x-3)
The resulting expression on factorization by grouping method is
(3-7x²)(x-3).
