Question

subtract 6x²-5x²+4x-2 from the sum of x+2x²-3x³ and 2-x²+6x-x³​

Answer 1

Answer:

Given-:

6x²-5x²+4x-2 -------(1)

x+2x²-3x³ -------(2)

2-x²+6x-x³ -------(3)

Step-by-step explanation:

Adding equation (1) and (2)

= x+2x²-3x³+2-x²+6x-x³

= 7x+x²-4x³+2 ------(4)

Subtracting equation (4) from equation (1)

= 6x²-5x²+4x-2-(7x+x²-4x³+2)

= 6x²-5x²+4x-2-7x-x²+4x³-2

= -3x+4x³-4
