The roots of a quadratic equation ax2+bx+c=0 are 3+sqrt2 and 3−sqrt2. find the values of b and c assuming that a=1.

Step-by-step explanation:

we know that

The general equation of a quadratic function in factored form is equal to

where

a is a coefficient of the leading term

x_1 and x_2 are the roots

we have

substitute

Applying the distributive property convert to expanded form

therefore

why do wages differ across industries

step-by-step explanation :

micro economists are concerned with economics on an industry or individual firm basis.

macro economists are concerned with national and international level

false

step-by-step explanation:

4y - 6 + 4y^2 - 9

before simplifying this contains 4 terms

after simplifying

4y -15 + 4y^2

it contains 3 terms
