Answer:
The answer to your question is below
Step-by-step explanation:
1.- (x + 2)(x + 4) = x² + 4x + 2x + 8 = x² + 6x + 8
2.- (m - 5)(m + 2) = m² + 2m - 5m - 10 = m² - 3m - 10
3.- (2x + 3)(4x - 2) = 8x² - 4x + 12x - 6 = 8x² + 8x - 6
4.- (2r - 3)(r + 12) = 2r² + 24r - 3r - 36 = 2r² + 21r - 36
6.- (k - 3)(k - 1) = k² - k - 3k + 3 = k² - 4k + 3
Answer:
2xc+5xc
Step-by-step explanation:
Since both y squared and 6y have a common factor of y, can put that to the side and divide both the y squared and 6y to get the second step of the work shown above. Separate both the y on the outside of the parentheses and the numbers within the parentheses and set them both equal to 0 as shown in step 3 of the work shown above. Finally solve for y as you would normally. Those two number in step 4 should be your final answer.
