Answer:
x^2 + 14x + 45
Step-by-step explanation:
(x + 5)(x + 9)
distribute x into the other equation and 5
x^2 +9x +5x + 45
add the common terms
x^2 + 14x + 45
done
Answer:
x^2+14x+45
Step-by-step explanation:
(x+5)(x+9)
x × x= x^2
x × 9= 9x
5 × x= 5x
5 × 9= 45
After multiplying everything
you collect like terms
x^2+9x+5x+45
5x and 9x have the same type of unknown so you add them
The end answer would be
x^2+14x+45
