Question

find the roots of the quadratic equation X square + 5 x + 3 is equal to zero using the quadratic formula​

Answer 1

Answer:

Step-by-step explanation:

X^2 + 5x +3 = 0

Here a = 1, b = 5, c = 3

Thus, x = (-b plus or minus √b^2 - 4ac) /2a

X= [-5 plus or minus √5^2 - 4(1)(3)]/2(1)

= (-5 plus or minus √25 - 12)/2

= (-5 plus or minus √13)/2

Thus roots are (-5 + √13)/2 and

(-5 - √13)/2.
