Answer:

x = 4, 2

Step-by-step explanation:

(x-2)(2x-3)=(x-2)(x+1)

\\\Rightarrow 2x^2-7x+6=x^2+x-2x-2\\\Rightarrow 2x^2-7x+6-x^2+x-2x-2=0\\\Rightarrow x^2-6x+8=0

While splitting the middle term the sum of the term should give us the middle term and their product should give the last term

\\\Rightarrow x^2-4x-2x+8=0

-4-2 = -6

-4\times -2=8

\\\Rightarrow (x-4)(x-2)=0\\\Rightarrow x=4, 2

Hence, x = 4, 2

Please help me with these!

No.4- This is not a triangle since one side should be less than the sum of the 2 other sides. In this case 8=3+5, hence it's equal & not smaller

N0.5- This is an isosceles triangle & there are an infinity of triangles with the mentioned degrees. (these are called similar triangle)

No6- This is a unique triangle

No.7- If the plane is parallel to the bases, then the slicing is a cercle.
 But if the plane (Parallelogram) is tilt, then the slicing is an ellipse
