4x² + 23x = -28

4x² + 23x + 28 = 0     move all terms to one side.

4x² + 16x + 7x + 28 = 0   split the second term into two terms

4x(x + 4) + 7(x + 4) = 0    factor.

(x + 4)(4x + 7) = 0    factor.

x = -4, -7/4

hope this helps, God bless!

Arrange the following polynomial into descending order for x, then interpret the degree of the 3rd term. 2xy4 + 2x2y − 3y2 + 10x
malfutka [58]
To arrange the given polynomial in descending order of x, we only look at the exponent of x in each term and then write it in decreasing order of the value. We do as follows:

2xy^4 + 2x^2y − 3y^2 + 10x^3<span>
10x^3 + 2x^2 + 2xy^4 - 3y^2

The degree of the third term would be 5. The degree of a term is the sum of the exponents of the variables involved in the term.
