Question

Decide 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

\(b^2-4ac\) is called 'Discriminant' which decides that whether the the quadratic equation can be solved by factoring.

Answer 2

I know that

Answer 3

So you need help factoring?

Answer 4

Basically

Answer 5

Well what numbers multiply to make 6 but add to make 7?

Answer 6

6 and 1

Answer 7

2x^+6x+x+3=0

Answer 8

ok now you have
(2x+6 )(2x+1)
Can you divide both of these by a GCF?

Answer 9

What number can we divide 2 and 6 by?

Answer 10

2

Answer 11

take common

Answer 12

You cant simpyfy anything more so you have
2x+3=0
2x+1=0
solve both for x

Answer 13

solve more
