Question

$3x + 5(2x + 6) - 7x$
What is the degree of this​

Answer 1

Answer:

Answer:

6 {x}^{2} + 7x - 3 = 06x

2

+7x−3=0

6 {x}^{2} - 2x + 9x - 3 = 06x

2

−2x+9x−3=0

2x(3x - 1) + 3(3x - 1) = 02x(3x−1)+3(3x−1)=0

(2x + 3)(3x - 1) = 0(2x+3)(3x−1)=0

either \: 2x + 3 = 0 \: or \: 3x - 1 = 0either2x+3=0or3x−1=0

$$\begin{lgathered}if \: 2x + 3 = 0 \\ 2x = - 3 \\ x = \frac{ - 3}{2}\end{lgathered}$$

$$\begin{lgathered}if \: 3x - 1 = 0 \\ 3x = 1 \\ x = \frac{1}{ 3}\end{lgathered}$$

$$x = \frac{ - 3}{2} or \: x = \frac{1}{3}$$

Answer 2

Degree of the polynomial => Highest power of the variable

Here Highest power of the variable (x) is 1 so, 1 is the degree.
