Hey can you me posted picture of question

(x+4)(x+5) = 0

Explanation:
The standard form of the quadratic equation is:
ax² + bx + c = 0

The given equation is:
x² + 20 = -9x
Adding 9x to both sides would make us reach the standard form which would be:
x² + 9x + 20 = 0
By comparison:
a = 1
b = 9
c = 20

To factor the equation, we would need to use the quadratic formula shown in the attached image.

By substitution, we ould find that:
either x = 

This means that the first factor is (x+4)

or x =

This means that the second factor is (x+5)

Based on the above, the factored form of the equation would be:
(x+4)(x+5) = 0

Hope this helps :)
