So the equation is 2x^2 + 7x + 3 = 0, let’s factor this out: 2x^2 + 6x + x + 3 = 0, so 2x(x+3) + 1(x+3) = 0, so (2x+1)(x+3)=0, so x = -1/2 or -3

The normal force acting on the legs of the table is 175 N

The weight of the books is the force exerted by the books on the table, and it is given as:

$W =25N$

The force exerted by the table is given as:

$F = 150N$

The parameters above imply that:

So, the normal force acting on the legs of the table is calculated as follows:

$F_N =F +W$

Substitute known values

$F_N = 150N + 25N$

$F_N = 175N$

Hence, the normal force acting on the legs of the table is 175 N
