Question

subtract 3x^2 7x-43x 2 7x−43, x, squared, plus, 7, x, minus, 4 from 8x^2-6x 28x 2 −6x 28, x, squared, minus, 6, x, plus, 2.

Answer 1

The result when we subtract 3x^2 + 7x - 4 from 8x^2 - 6x + 2 is 5x^2 - 13x + 6.

Subtracting polynomials is a method of subtracting polynomials by converting the signs to the opposite sign. It is done in two methods - vertically and horizontally.

Using the method in subtracting polynomials horizontally:

Step 1: Arrange the polynomials in their standard form.

Both 3x^2 + 7x - 4 and 8x^2 - 6x + 2 are in their standard form(exponents in decreasing order)

Step 2: Place the polynomial next to each other horizontally.

(8x^2 - 6x + 2) - (3x^2 + 7x - 4)

Step 3: Distribute the negative sign to the second polynomial.

(8x^2 - 6x + 2) - 3x^2 - 7x + 4

Step 4: Combine the like terms and arrange them in decreasing order.

8x^2 - 3x^2 - 6x - 7x + 2 + 4

Step 5: Perform the calculations.

5x^2 - 13x + 6
