Question

what must be subtracted from a cube -4a square+5a-6 to obtain a square -2a+1 please tell the answer fast​

Answer 1

Answer:

Step-by-step explanation:

Let the value to be found be x

a³ - 4a² + 5a - 6 - x = a² - 2a + 1

x = a² - 2a + 1 - a³ + 4a² - 5a + 6

x = a² + 4a² - 2a - 5a + 1 + 6 - a³

x = 5a² - 7a + 7 - a³

x = -a³ + 5a² - 7a + 7
