Answer:
OPTION A
Sure for help ,
Standard form of a polynomial
A standard form of a polynomial of degree 1 = a x + b = 0
A standard form of a polynomial of degree 2 = a x² + b x + c = 0 .
And so on ...
Option verification :
OPTION a )
- 7 + 6 y + 5 y² .
The equation in standard form is :
5 y² + 6 y - 7
Here the leading coefficient is 5 .
So the correct answer is OPTION a )
OPTION b )
5 y + 3 y² - 4
This when written in standard form is :
⇒ 3 y² + 5 y - 4
The leading coefficient is 3 .
OPTION c )
The equation written in standard form is :
- 5 x³ + x² + 2 x
Here leading coefficient is - 5 .
OPTION d )
The equation is already in standard form .
x + 5 has leading coeffecient of 1 .
Step-by-step explanation:
Coefficient of a term is the value multiplied to it .
For example : coefficient of 5 x² is 5 .
The leading coefficient has the highest power .
By comparing it to the standard form viz.
ax^2 + by + c = 0
5y^2 + 6y - 7 =0
Hence, it has leading coefficient 5
Therefore, option 'a' is the correct one
