The factored expression of the polynomial expression given as: x^2 - 3x - 18 is (x + 3)(x - 6)
<h3>How to match the
polynomial?</h3>
The polynomial expression is given as:
x^2 - 3x - 18
Express -3x as 3x - 6x
So, we have:
x^2 + 3x - 6x - 18
Factorize the polynomial expression
x(x + 3) - 6(x + 3)
Factor out x + 3
(x + 3)(x - 6)
Hence, the factored expression of the polynomial expression given as: x^2 - 3x - 18 is (x + 3)(x - 6)

Answer:
1). 2x^2-3x+20
2). 4x^2-14x+6
Step-by-step explanation:
1. (x-4)(2x+5)
FOIL:
(x)(2x)+5(x)-8(x)+(4)(5)
2x^2+5x-8x+20
=2x^2-3x+20
2. (4x-2)(x-3)
FOIL:
(4x)(x)-(3)(4x)-2(x)-2(-3)
4x^2-12x-2x+6
=4x^2-14x+6
Answer:
1.25315*102
Step-by-step explanation:
It is 1/11 or 4/44.
Explained:
This is because when you subtract 26 and 22 you get 4 and when you subtract 4 and -45. The 45 then becomes a positive since when you get a negative and a negative you get a positive. Then you simplify it by 11.
20.75 because if you add 4.85+7.95+7.95 add that you get 20.75
