Answer:

x² +14x-15=0

=>x²+15x-x-15=0

=> x(x +15)-1(x+15)=0

=> (x-1)(x+15)=0

=> x = 1 or,x=-15

Answer: x = 1

Step-by-step explanation:

x^2 + 14x - 15 = 0

x^2 + 14x = 15

x^ + 14x = 15

1 + 14 = 15

So X must = 1

because 14 + 1 = 15

hope this helps mark me brainliest if it did

Westkost [7]

As a rule , - times - = + and - times + = -

$\begin{gathered} -16m^2n-(-25m^2n)+(-7m^2n\text{ ) } \\ =-16m^2n+25m^2n-7m^2n\text{ ( based on the rule above )} \\ =+9m^2n-7m^2n\text{ ( -16 + 25 = + 9 )} \\ =+2m^2n \end{gathered}$

Therefore the correct answer to the question is 2m squared n
