1. Subtract the largest number with the smallest number... e.g. 100 - 25

2. Divide the range by 5 and 10... e.g 75/10= 7.5 75/5=15

3. Pick the number between 5 and 10... e.g. 7.5

4. Round to the largest whole number... e.g. 8

5. Add 8 to the smallest number of the range 5 times... e.g. 25 + 8, 33 +8, etc

6. You'll want to have it so the previous number becomes your beginning of your intervals... e.g. 25-33, 33-41, 41-49, 49-57, 57-65.

6. Fill your histogram

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

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:

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

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

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