Here is your answer

a) x=-2, -3

REASON :
$f(x)= {x}^{2}+5x+6$

= ${x}^{2}+2x+3x+6$

= $x(x+2)+3(x+2)$

= $(x+2)(x+3)$

To find zeroes

f(x)= 0

So,

(x+2)(x+3)=0

$x=-2 or x=-3$

You bought a magazine for $3 and two notepads. You spent a total of $13. How much did each notepad cost? *

Answer:

Step-by-step explanation:

We want to find the cost of a notepad considering a magazine costs $3 and we buy 2 notepads and the total cost of the magazine and the 2 notepads is $13 so we can set up an equation to represent this situation. Let 'n' be notepads and that's the value we are solving for so,

⇒ Form the equation

→ 2n + 3 = 13

⇒ Minus 3 from both sides to isolate 2n

→ 2n = 10

⇒ Divide both sides by 2 to find the cost of one notepad

→ n = 5

The cost of one notepad is $5 considering that a magazine cost's $3 and two notepads and total is $13.
