Question

Solve for x in the equation x2 + 10x+12 = 36

Answer 1

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

Answer: Option 1

Explanation:

Given:

$\left[x^{2}+10 x+12\right]=36$

To Find:

  The possible value of x in the above equation

Solution:

Given equation;$\left[x^{2}+10 x+12\right]=36$

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

$\left[(-12)^{2}+10(-12)+12\right]=36$

[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
