If a and b are the zeros of the quadratic polynomial 4x2+4x+1, find the value of a/b+b/a?

kow [346]

Answer:

Step-by-step explanation:

First you need to factor your quadratic equation. You'll get (2x+1)(2x+1). Your two zeroes will be -1/2 and -1/2 with one being a, the other b. So then

a/b = (-1/2)/(-1/2)

and

b/a = (-1/2)/(-1/2)

Both reduce to 1. So a/b + b/a is 1+1=2

100 POINTS! I REALLY NEED TO GET THIS CORRECT! Factor the quadratic trinomial.

Assoli18 [71]

The factors of the equation $x^2-3x-18$ are $(x-6)(x+3)$

Step-by-step explanation:

We need to factor the quadratic trinomial. $x^2-3x-18$

We will do factorization by braking the middle term such that adding those number we get middle term (-3x) and multiplying those numbers we get (-18x^2)

Solving:

$x^2-3x-18\\=x^2-6x+3x-18\\=x(x-6)+3(x-6)\\=(x-6)(x+3)$
