f(x) = x² + 5x, evaluate f(-2),

f(-2) = (-2)^2 + 5(-2)

f(-2) = 4 - 10

f(-2) = - 6

f(-2) = (-2)^2 + 5(-2)

f(-2) = 4 - 10

f(-2) = - 6

|p + 2| = 10;

p + 2 = 10;

p = 10 - 2;

p = 8;

-(p + 2) = 10;

-p - 2 = 10;

-p = 10 + 2;

-p = 12;

p = -12;

|8 + 2| = 10;

10 = 10;

|-12 + 2| = 10;

10 = 10

p + 2 = 10;

p = 10 - 2;

p = 8;

-(p + 2) = 10;

-p - 2 = 10;

-p = 10 + 2;

-p = 12;

p = -12;

|8 + 2| = 10;

10 = 10;

|-12 + 2| = 10;

10 = 10

5x/8 + 10 = 2;

5x/8 = 2 - 10;

5x/8 = -8;

5x = -8 * 8;

5x = -64;

x = -64/5

5x/8 = 2 - 10;

5x/8 = -8;

5x = -8 * 8;

5x = -64;

x = -64/5
