2x³ + x² - 5x + 2

(2x³ + 3x - 2)(x - 1)   

(2x³ + 4x - x - 2)(x - 1)

(2x(x + 2) - (x + 2))(x - 1)

(x + 2)(2x - 1)(x - 1)

so x + 2 is not a factor of the polynomial!

hope this helped, God bless!

Evaluate [16 ÷ (2 + 3 • 2)] + [4 • (36 – 25)]
maw [93]

Answer:

46

Step-by-step explanation:

There is an open + in the middle. It does not have any brackets around it. Therefore you do it at the very last.

Left side of the plus sign.

[16 ÷ (2 + 3*2)] Do the multiplication inside the parenthesis ( 2*3) first.

= [16 ÷ (2 + 6)] Add inside the parenthesis.

= [16 ÷ 8 ]         Do the division

= 2

Right side of the open plus sign

[4 * (36 - 25)]   Do the subtraction first.

[4 * 11 ]             Do the multiplication

44

Now combine both right and left side.

2 + 44

46

The answer is 46.
