Question

Find the roots of quadratic equation ​

Answer 1

x^2 + 5 x + 6

X square + 6 x minus x + 6

X(X+6)+1(X+6)

(X+1)(X+6)

zeros are minus 1 and minus 6

Answer 2

Answer:

x² + 5x + 6 = 0

=> x² + 2x + 3x + 6 = 0

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

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

=> x + 2 = 0 or x + 3 = 0

=> x = - 2 or x = - 3

so the roots are - 2, - 3
