Answer:
Step-by-step explanation:
An isosceles triangle needs to have 2 congruent sides to be considered a isosceles triangle. To find the length of AB use Pythagorean theorem :
a^2+b^2=c^2
substitute the triangle's lengths which are given and you get:
3^2 + 3 ^2= c^2
simplify and you get
c= √18
Repeat for AC and you get the same thing: √18.
AB=AC=√18. The triangle is an isosceles triangle because you have 2 congruent sides.
You can get all the terms on one side, and then solve for x by any means:

Factor out a -2:

Factor this equation:

I will use the AC method. To use it, first multiply a and c (in ax^2 + bx +c):

Now, look for two numbers that multiply to -12 and add to -11. Obviously these numbers are -12 and 1. (-12*1 = -12 and -12+1 = -11). Now, because of rules, you set it up in a Punnett square:
4x^2 -12x
x -3
Now, we find common factors of the terms in rows:
_x_______-3__
4x| 4x^2 -12x
1 | x -3
So, you can use this to write an equivalent expression to the quadratic given:

Now, we known the factors are (solve for x):
3 and -1/4.
