So discriminant gives us 3 possibilites connected with result of the equation b^2-4ac. If it is bigger than zero, there are 2 solutions, if answer is exactly 0, then there is one answer and if the number is lower than 0, there are no solutions.
Discriminant of your quadratic equation is (-4)^2-4*1*5=16-20=-4, so there are no solutions.
B
Because the its follows the pattern also b isn’t negative
Answer:
6(2x+3)
Step-by-step explanation:
12x +18
Factor out 6 from each term
6*2x+ 6*3
6(2x+3)
