A. x – 9
B. x – 2
C. x + 5
D. x + 7
Factorize the quadratic trinomial by the rule:
1. Find the roots:
2. Factorize the polynomial:
3. Only factor x-2 is given in options, then the correct choice is B.
The factor of the given polynomial expression is (x - 2). So, option B.
Using variables and coefficients, polynomials are algebraic expressions. The word indeterminates is sometimes used to describe variables.
For polynomial expressions, addition, subtraction, multiplication, and positive integer exponents are all mathematical operations that are possible, however division by variables is not one of them.
The given polynomial expression is,
x²- 9x + 14
So, we can write that,
(x - a) (x - b) = x²- 9x + 14
So, we can write two equations,
ab = 14
a + b = 9
Therefore, we can say that,
a = 2 and b = 7
Therefore, the factors of the given polynomial expression is,
(x - 2) (x - 7) = x²- 9x + 14

29
B.
–29
think its A=29
Yep its A) 29
because that symbol is the absolute value symbol meaning its is always turned into a positive.
