Question

If x1 and x2 are solutions to 3x^2+15x+9=0 quadratic equation, then

x1*x2 =

Answer 1

x₁ × x₂ = 3

Explanation:

given a quadratic equation in standard form

ax² + bx + c = 0 (a ≠ 0 )

then the product of the roots =
`(c)/(a)`

3x² + 15x + 9 = 0 ← is in standard form

with a = 3 and c = 9 , then

x₁ × x₂ =
`(9)/(3)` = 3
