Subtract the following polynomials, then place the answer in the proper location on the grid. Write the answer in descending powers of x.
(-6.7x2power + 2.3x y + 5.2) - (-14.9x 2 - 3.5x y + 7.1)
my answer 8.2x2power+5.8xy-1.9
To subtract the given polynomials: (-6.7x^2 + 2.3xy + 5.2) - (-14.9x^2 - 3.5xy + 7.1), you can follow these steps:
Step 1: Distribute the negative sign to each term in the second polynomial:
(-6.7x^2 + 2.3xy + 5.2) + (14.9x^2 + 3.5xy - 7.1)
Step 2: Combine like terms by adding or subtracting coefficients of terms with the same variables raised to the same powers:
(-6.7x^2 + 14.9x^2) + (2.3xy + 3.5xy) + (5.2 - 7.1)
(8.2x^2) + (5.8xy) + (-1.9)
So, the subtraction of the given polynomials is: 8.2x^2 + 5.8xy - 1.9.
Your answer, 8.2x^2 + 5.8xy - 1.9, is correct.
I agree, good job
thank you
question(6x + 1)(5x + 8)
my answer30x2power+53x+8
yup, correct again
(instead of 30x2power
we can type 30x^2 on here)
