Multiply (x^2+x+1)(x-1)

Mathematics
1 answer:
marysya [2.9K]3 years ago

Answer:

x^3 - 1

Step-by-step explanation:

(x^2 + x + 1) (x - 1)

Here we have to use the distributive property.

(x^2 + x + 1)x -1(x^2 + x + 1)

Now distribute x and -1 inside the parenthesis, we get

x^3 + x^2 + x -x^2 - x - 1

Now we have to simplify the like terms.

x^3 + x^2 -x^2 + x - x -1                  [x^2 - x^2 =0; x -x = 0]

= x^3 - 1

The answer is x^3 - 1

Thank you.

Answer: ∠ABE=20°

Step-by-step explanation:

∵ AB=BC

∴ ΔABC is a isosceles triangle

∵ ∠A=30

∴ ∠C=30

∵ The interior angle sum of triangle is 180°

∵ ∠A+∠B+∠C=180

    30+∠B+30=180

           ∠B+60=180

                  ∠B=120 (∠ABC)

∵ ∠EBD+∠ABE+∠ABC=linear pair

∴∠EBD+∠ABE+∠ABC=180°

                  4x+2x+120=180

                        6x+120=180

                                6x=60

                                  x=10

∠ABE=2x=2(10)=20°

Hope this helps!! :)
