Question

x2+5x+6=o find the root of the quadratic equation

Answer 1

Step-by-step explanation:

GIVEN:

x^2 + 5x + 6 = 0

SOLUTION:

=> x^2 +3x +2x +6 = 0

=> x(x+3) + 2(x+3) = 0

=> (x+2) (x+3) = 0

So,

either x = -3

or x = -2

VERIFICATION:

=> -3×-3 + 5×-3 +6 => -2 × -2 + 5×-2 + 6

= 9 - 15 +6 = 4 - 10 + 6

= 0 . = 0
