Help

Solve the quadratic equation by any means. Identify the method and complete the explanation of why you chose it. Irrational answers may be left in radical form.

5x2 + 16x + 3 = 0

Part a: factoring
Completing the swuares

Taking the square roots
Which one


Part b:

Why:
There are not many factors to check
It is not factorable
B is = to zero

Answer 1

Factoring:
`x = -(1)/(5), -3`

Explanation:

A) You can factor the expression
`5x^2 + 16x + 3` into
`(5x+1)(x+3)`.

5x + 1 = 0 and x + 3 = 0

`x = -(1)/(5), -3`

B) I would use factoring because you can factor this expression, and you don't have to use completing the square
