y = 6 x 2 + 24 x − 192 y = 0 ⇔ 6 x 2 + 24 x − 192 = 0 / : 6 x 2 + 4 x − 27 = 0 x 2 + 2 ⋅ 2 ⋅ x + 2 2 − 2 2 − 27 = 0 ( x + 2 ) 2 − 31 = 0 ( x + 2 ) 2 = 31 ⇔ ( x + 2 = 31 or x + 2 = − 31 ) x = − 2 + 31 or x = − 2 − 31
To factor the equation y = 6 x 2 + 24 x − 192 , we simplify it to ( x + 8 ) ( x − 4 ) = 0 . The zeros are x = − 8 and x = 4 .
