Question

Okay i dont understand what they are asking me to do Which part of the quadratic formula tells you whether the quadratic equation can be solved by factoring?

-b b2 - 4ac 2a

Use the part of the quadratic formula that you chose above and find its value given the following quadratic equation:

2x2 + 7x + 3 = 0

Answer 1

b2 - 4ac
for 2x2 + 7x + 3 = 0
b2 - 4ac= 7^2 - 4*3*2 = 25

Answer 2

Discriminant tells us if a quadratic equation can be solved or not.
\[D=b^2-4ac\]
option b

Answer 3

\[b ^{2}-4ac\]
is termed the discriminant and if that value:
is positive the equation has two real solutions
is 0 the equation has one (repeated) solution
is negative the equation has no real solutions (solutions are complex numbers)
