Question

Subtract 4x - 2x^2 -2 from the sum of the polynomials x^2 + 3x -2, 3x^2 - x.

Plz help fast

Answer 1

Sum:

(x²+3x-2)+(3x²-x)

by removing the brackets,

x²+3x-2+3x²-x

by grouping the like terms

x²+3x²+3x-x-2

4x²+2x-2

Subtraction:

according to the question,

(4x²+2x-2)-(4x-2x²)

here the signs change for 4x-2x² as (-) is outside the bracket

by removing the brackets now,

4x²+2x-2-4x+2x²

by grouping the like terms

4x²+2x²+2x-4x-2

6x²-2x-2

hope it helps

have a great day
