The diagram shows a parallelogram, angles 3x-15, 2x , 2x , 2x +24 work out x

The  value of x is 39°.

A parallelogram is a quadrilateral with equal and parallel opposite sides.

That is ∠A = ∠C, ∠D = ∠B.

That is ∠A + ∠B + ∠C + ∠D = 360°.

That is ∠A + ∠B = 180°, ∠B + ∠C = 180°,∠C + ∠D = 180°, ∠D + ∠A = 180°

We have angles of parallelogram as

∠A= 3x-15,

∠B = 2x ,

∠C = 2x ,

∠D = 2x +24

So, 3x-15+2x+2x+2x +24 = 360°

9x+9= 360°

9(x+1) = 360°

(x+1) = 40°

x = 39°

Therefore the value of x is 39°.

Parallelogram has two pairs of congruent angles.

Therefore we have the equation:

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
