Answer: 21[tex]x^{2}[/tex] - 52x - 48
Step-by-step explanation:
Using the expanding rule we get
5x * 3x - 5x * 10 + (6[tex]x^{2}[/tex] - 18x + 16x -48)
15[tex]x^{2}[/tex] - 50x + 6[tex]x^{2}[/tex] - 2x - 48
21[tex]x^{2}[/tex] - 52x - 48
Answer:
21x^2-52x-48
5x(3x-10) + (2x-6)(3x+8)
Distribute
5x^2 -50x+6x^2-2x-48
Combine like terms
21x^2-50x-2x-48
