\bf{1) \  x^4-61x^2+900=0 }

Applying the factorization method, for example:

      \bf{ 0=(x^2)^2-61(x^2)+900=(x^2-36)(x^2-25)}

               \bf{\\ &=(x+6)(x-6)(x+5)(x-5);    }

              \bf{ x_1=6 \quad x_2=-6 \quad \ \ \ x_3=5 \quad x_4=5  }

\bf{2) \  x^4-25x^2+144=0  }

Applying the factorization method:

          \bf{0&=(x^2)^2-25(x^2)+144=(x^2-16)(x^2-9) }

             \bf{ =(x-4)(x+4)(x-3)(x+3); }

            \bf{ x_1=4 \quad x_2=-4 \quad x_3=3 \quad x_4=-3  }

It's not a college assignment!
Kisachek [45]

Using a calculator, the equation for the line of best fit where x represents the month and y represents the time is given by:

a. y = −1.74x + 46.6

<h3>How to find the equation of linear regression using a calculator?</h3>

To find the equation, we need to insert the points (x,y) in the calculator.

For this problem, the points (x,y) are given as follows, from the given table:

(1, 46), (2, 42), (3,40), (4, 41), (5, 38), (6,36).

Hence, inserting these points in the calculator, the equation for the line of best fit where x represents the month and y represents the time is given by:

a. y = −1.74x + 46.6
