Exercise 57 Page 175

We can write a quadratic equation in factored form using the given roots. Then we will change it to standard form by multiplying the factors. Factored Form:& a(x-p)(x-q)=0 Standard Form:& ax^2+bx+c=0 In the factored form, p and q are the roots of the equation. Since we are told the roots are 3.4 and 0.6, we can partially write the factored form of our equation. a( x- 3.4 ) ( x-0.6 )=0 Since a does not have any effect on the roots, we can choose any value. For simplicity and in order to have integer coefficients, we will let a=100. This will allow us to eliminate the decimals when we distribute. 100( x- 3.4 ) ( x-0.6 )=0 Finally, let's use the Distributive Property to obtain the standard form.

Please note that this is just one example of a quadratic function that satisfies the given requirements.
