# Solve the Following Equation: 3x2 + 25 X + 42 = 0 - Mathematics

Sum

Solve the following equation: 3x2 + 25 x + 42 = 0

#### Solution

3x2 + 25 x + 42 = 0

"x"^2 + 25/3 "x" + 14 = 0

"x"^2 + 6"x" + 7/3 "x" + 14 = 0

"x"("x" + 6) + 7/3 ("x" + 6) = 0

("x" + 6)("x" + 7/3) = 0

(x + 6) = 0 , ("x" + 7/3) = 0

x = -6 , x = -7/3
