Answer:
Given the equation:
A quadratic equation is in the form: where a, b ,c are the coefficient and a≠0 then the solution is given by :
......[1]
On comparing with given equation we get;
a =3 , b = 10
then, substitute these in equation [1] to solve for c;
Simplify:
Also, it is given that the difference of two roots of the given equation is
i.e,
Here,
, ......[2]
.....[3]
then;
simplify:
or
Squaring both sides we get;
Subtract 100 from both sides, we get
Simplify:
-12c = -96
Divide both sides by -12 we get;
c = 8
Substitute the value of c in equation [2] and [3]; to solve
or
or
Simplify:
Now, to solve for ;
or
or
Simplify:
therefore, the solution for the given equation is: and -2.
The first is a right triangle because there is a right angle, and it is scalene because none of the sides are congruent.
The second is an obtuse triangle because there is an obtuse angle, and it is an isosceles triangle because two of the sides are congruent.
The third is an acute triangle because all of the angles are acute, and it is an <span>isosceles triangle because two of the sides are congruent.
The fourth is a right triangle because it has a right angle, and it is a s</span><span>calene because none of the sides are congruent.</span>
