I need help with problems 7-17, showing all work, Thank you
Add and subtract the polynomials and simplify: 7. (5x 2 + 6x-2)+(3x-2x+ 4) 8. (4x2-7x+1)-(x+9x-2) 9. (3x 2 + 2x + 8) + (9x2+7x -1) 10. (2x 2-5x -3) -(6x2-4x-8) 11. (7x-3) +(5x-4) 12. (2x+ 6)-(8x+9) Multiply the polynomials and simplify: 13. (7x 3-89(9/ + 5x-x) 14. (5x 3) (6x2+ 2x-9) 15. (10x+ 7) (6x-8) 16. (9x+ 4) (3x2-1) 17.(8x 3-2x2+ 3x) (Bx 2+ 7x-5) Solve each quadratic equation through factoring: 18, x 2 + 4x + 4 = 0 19. x2-14x+49 0 20. y2+ 7y-60 0 21. Ñ (x-3)-18 22, x 2 = 12x-36 23. 5x 2 20x
