Solve for x in the equation x2 + 10x+12 = 36
х = –12 оr x = 2
x = -11 or x = 1
x = -2 or x = 12
x = -1 or x = 11

The possible answer for the above equation is x=-12 or x=2

Option 1

Explanation:

Given:

To Find:

  The possible value of x in the above equation

Solution:

Given equation;

By using the options given the question we get

Option 1; If x=-12 0r x=2

Substitute these value in the equation we get

[144-120+12]=36

[24+12]=36

36=36  

Thus both the L.H.S=R.H.S

Hence Option 1 gives the correct value of x

Result:

Thus the possible value for x in the above equation is x=-12 or x=2

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
