I need help on questions 8,9 and 10!! http://static.k12.com/eli/bb/1211/5_68981/1_124249_20_69001/fd27e95748792f7c2f1d1f347a2cd56e6750b95d/media/7c533c33854b5d80d74ef525470a41d5dc1f7aba/AAHS_M5S5L8_1_teacher_graded_assignment_PROJECTGUIDE.pdf
@dg2
post first question
for there to be 2 solutions the discriminant must be more than 0
for ther to be 1 solution, the discriminant must equal zero for there to be no solutions, the discriminant must be less than zero lol just had a quadratics test today
okay one sec
Think of another quadratic equation that has two (2) real number solutions. Write the equation in ax^2+ bx+ c =0 form. Then find the value of the discriminant to support your answer.
ok so the discriminat must be more than 0
Follow the directions for each problem to write a quadratic equation that has the given number of solutions. Be sure to show all the work leading to your answer. those are the directions
For example \[x^2 +3x+3=0\] therefore the discriminant of the equation =\[b^2 - 4ac\] =\[3^2 - 4\times1\times2\] =1 Because the discriminant (1) is more than zero, therefore there are two solutions
oh okay i kinda get it
#9?
When Discriminant = 0, it has 2 real and equal solutions When Discriminant > 0, it has 2 real solutions When Discriminant < 0, it has 0 real solutions
thanks for the tip:)
