Question

7x ^ 3 + sx + 4x ^ 5 + 2xwri + c + he degree of + his Polynomial.​

Answer 1

Answer:

Correct option is D)

5x

3

+4x

2

+7x

The degree is the value of the greatest exponent of any expression (except the constant ) in the polynomial.

Here, term with greatest exponent =5x

3

exponent of this term =3

Thus, degree =3

Answer 2

Answer:

x(2x²-x+2)(2x²+x+2)

Step-by-step explanation:

7x³+x+4x⁵+2x+x

7x³+4x+4x⁵

rearrange terms- 7x³+4x+4x⁵

4x⁵+7x³+4x

find one factor

factor by grouping

x(4x⁴+7x²+4)

factor on factor

factor by grouping

x(2x²-x-2)(2x²+x+2)
