Question

The roots of the quadratic equation. x^2+4x+3=0 are...... ​

Answer 1

Answer:

The roots are negative. That is we have the roots as - 1 and - 3. The roots are unequal and imaginary.

Step-by-step explanation:

Answer 2

Step-by-step explanation:

The best way to solve quadratic equations (ax squared + bx — c = 0) is by using the quadratic formula. My cell phone doesn't have the required signs, so let me put up a picture.

So in your equation, b = -4, a = 1, & c = 3.

Hence,

-b would be —(-4) = +4,

b squared would be -4 x -4 = 16,

4ac would be 4 x 1 x 3 = 12,

& 2a would be 2 x 1 = 2.

So, the quadratic formula for your equation would look like this:

Or, simply put:

So, the answers to your question are:

(4 + 2) ÷ 2 = 6 ÷ 2 = 3

Or,

(4 — 2) ÷ 2 = 2 ÷ 2 = 1

Hence, the solutions to your equation are 3 and 1.

Hope it helps, & good luck!
