Fill in the missing number to complete the factorization
x3 + x2 - 21x - 45 = (x + 3)(x - 5)(x +

3

Step-by-step explanation:

Let the missing number be .

Then we have

We expand the right hand side to get:

By comparing constant terms we get:

Divide both sides by -15

Therefore the missing number is 3

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.

step-by-step explanation:

a rhombus is a parallelogram enjoying his symmetry.
