Question

(x²-2x-15)-(-13+17x-7x²)​

Answer 1

Answer:

8x^2-19x-2

Step-by-step explanation:

x^2-2x-15+13-17x+7x^2

=8x^2-19x-2

Answer 2

(x2−2x−15)−(−13+17x−7x2)



-13+17x-7x^{2}

x^{2}-2x-15+13-17x+7x^{2}x2−2x−15+13−17x+7x2



-1513-2

x^{2}-2x-2-17x+7x^{2}x2−2x−2−17x+7x2



-2x-17x-19x

x^{2}-19x-2+7x^{2}x2−19x−2+7x2



x^{2}7x^{2}8x^{2}

8x^{2}-19x-28x2−19x−2
