Question

What is the discriminant of 3х2 + 6x = 27

Answer 1

`\displaystyle\\ 3x^2+6x=27\\\\ 3x^2+6x-27=0\\\\\text{The discriminant is:}\\\\\Delta=b^2-4ac\\\\\Delta=6^2-4\cdot3\cdot(-27)\\\\\Delta=6^2+4\cdot3\cdot27\\\\\Delta=36+4\cdot81\\\\\Delta=36+324\\\\\boxed{\bf\Delta=360}`

.

Answer 2

B^2 - 4ac
A= 3
B= 6
C= -27

36 - 4(3)(-27)
36+324
360
Because it is positive you will have 2 solutions
