Question:
is x=-3 is a solution of the equation 2xsqyare 5x 3=0
Answer:

Given, equation is:

      2x2 + 5x + 3 = 0

=> 2x2 + 2x + 3x + 3 = 0

=> 2x(x + 1) + 3(x + 1) = 0

=> (x + 1)*(2x + 3) = 0

=> x + 1 = 0 and 2x + 3 = 0

=> x = -1, -3/2

So, x = -3 is not a solution of the equation 2x2 + 5x + 3 = 0
