You did not Include the statements.
It’s 55
Because x= 5 and 11•5= 55
If it isn’t this i’m going to cry in a corner.
x^2 - 75 = -10x
<em><u>Add 10x to both sides.</u></em>
x^2 + 10x - 75
<em><u>Check if splitting the middle term is possible.</u></em>
<em><u>Display factors of -75.</u></em>
1 * -75
-1 * 75
-5 * 15 < (this meets the criteria)
<em><u>Split the middle term.</u></em>
x^2 - 5x + 15x - 75
<em><u>Factor each binomial.</u></em>
x(x - 5) + 15(x - 5)
<em><u>Combine factors.</u></em>
(x + 15)(x - 5) is the completely factored form of the provided quadratic.
