From the sum of 4x²−7x+5 and −7x²−8x+3 subtract 2x²−7x+9.�

1.	From the sum of 4x²−7x+5 and −7x²−8x+3 subtract 2x²−7x+9.
Answer» ANSWER: 5x² + 8x + 1 Step-by-step explanation: 1 step) = (4x² - 7x + 5) + ( - 7x² - 8x + 3) = 4x² - 7x + 5 - 7x² - 8x + 3 = 4x² - 7x² - 7x - 8x + 5 + 3 = -3x² - 15X + 8 2 step) = ( 2x² - 7x + 9 ) - ( - 3x² - 15x + 8) = 2x² - 7x + 9 + 3x² + 15x - 8 = 2x² + 3x² - 7x + 15x + 9 - 8 = 5x² + 8x + 1 Hope it helps you.. Good Morning ✌️ Have a NICE Day

From the sum of 4x²−7x+5 and −7x²−8x+3 subtract 2x²−7x+9.

Answer»

Step-by-step explanation:

1 step) = (4x² - 7x + 5) + ( - 7x² - 8x + 3)

= 4x² - 7x + 5 - 7x² - 8x + 3

= 4x² - 7x² - 7x - 8x + 5 + 3

= -3x² - 15X + 8

2 step) = ( 2x² - 7x + 9 ) - ( - 3x² - 15x + 8)

= 2x² - 7x + 9 + 3x² + 15x - 8

= 2x² + 3x² - 7x + 15x + 9 - 8

= 5x² + 8x + 1

Hope it helps you..

Good Morning ✌️

Have a NICE Day
