If we have a triangle with sides a,b,c then
b-a < c < b+a
describes the restriction of the length of side c, given sides a and b. This is due to the triangle inequality theorem.
a = 6
b = 9
b-a < c < b+a
9-6 < c < 9+6
3 < c < 15
<h3>Answer: The third side is between 3 cm and 15 cm. The third side cannot equal 3 cm, and it also cannot equal 15 cm. </h3>
If a quadratic equation has solutions
and
, then we can write it as

So, in your case, we have (let me write 1.5 as 3/2 and -0.25 as -1/4)

If we don't want decimal coefficient, we can multiply the whole expression by 8:
