PLS HURRY! 9TH GRADE ALGEBRA :/ (edmentummmm) I AM GIVING BRAINLIEST FOR CORRECT ANSWERS!!

Answer 1

Answer:

• Option A (-26x² + 56x - 15) is correct.

Step-by-step explanation:

• [3x(-2x + 7)] - [5(x - 1)(4x - 3)]
• => [-6x² + 21x] - [(5)(x - 1)(4x - 3)]
• => [-6x² + 21x] - [(5x - 5)(4x - 3)]
• => [-6x² + 21x] - [20x² - 15x - 20x + 15]
• => -6x² + 21x - 20x² + 15x + 20x - 15
• => -26x² + 56x - 15

Hence, Option A (-26x² + 56x - 15) is correct.

Hoped this helped.
