Subtract: -3p² + 3pq + 3px from 3p (-p - a - r)

Solution:

Given, subtract -3p² + 3pq + 3px from 3p (- p - a - r)

⇒ 3p (-p - a - r) - (-3p² + 3pq + 3px)

= -3p² - 3pa -3pr - (-3p² + 3pq + 3px)

= -3p² + 3p² - 3pa - 3pr - 3pq - 3px

= -3pa - 3pr - 3pq - 3px

✦ Try This: Subtract: -5x² + 4xy + 5xp from 2x(3x - 2y - p)

Given, subtract -5x² + 4xy + 5xp from 2x(3x - 2y - p)

⇒ 2x(3x - 2y - p) - [-5x² + 4xy + 5xp]

= 6x² - 4xy - 2xp + 5x² - 4xy - 5xp

= 6x² + 5x² - 4xy - 4xy - 2xp - 5xp

= 11x² - 8xy - 7xp
