(13x^2 - 10x + 12) - (9x^2 + 20x - 50)

13x^2 - 10x + 12 - 9x^2 - 20x + 50

13x^2 - 9x^2 = <em>4x^2</em>

- 10x - 20x = <em>-30x</em>

12 + 50 = <em>62</em>

4x^2 - 30x + 62

Solve, 3y(4y−1)−2y(6y−5)=9y−8(3+y)
igomit [66]

Answer:

3y(4y-1)-2y(6y-5)=9y-8(3+y)

12y∧2-3y-12y∧2+10y=9y-24-8y

12y∧2-12y∧2-3y+10y=9y-8y-24

7y=y-24

7y-y=-24

6y=-24

y=-24/6=-4
