Answer:
x+6 and x+7
Step-by-step explanation:
Given the quadratic equation;
x^2 + 13x + 42
Factorize
x^2+13x+42 = 0
x^2 + 7x + 6x + 42 = 0
x(x+7)+6(x+7) = 0
(x+6)(x+7) =0
Hence the required binomials are x+6 and x+7
The answer you are looking for is associative property of addition.
In associative property, no matter where the parenthesis are, a + (b + c) is going to be equal to (a + b) + c. Since the parenthesis follow the equation a + (b + c) = (a + b) + c, you can assume you are using the associative property. Lastly, add "of addition" to associative property, since you are using addition, not multiplication.
I hope this helps!
Combine like terms (5y and -y= 4y) and the simplest form would be 4y+7
