Explanation

Answer

Problem

Determine the number of real solutions of the equation:
\$7x^2 + 4x + 3 = 0 \$

Step

Now compare the given equation with

\$ax^2+bx+c=0\$

Step

substitute the values

\$ " a = 7,b = 4,c = 3" \$

Formula:

formula

\$ b^2 - 4ac = 0 \$

Step

By simplfying

\$ 4^2 - 4(7)(3) \$

Step

After simplification we get

\$16 - 84 \$

Step

The discriminant is less than 0

\$ - 68 < 0 \$
