Question

Decide the Quadratic equations in the following : —
(1) x²+5= 33
(2) y³+9y²+5=0
(3) 8m²+3m-6=500
(4) 5a+9a²-0=0​

Answer 1

Answer:

1,3,4

Step-by-step explanation:

x²+5=33

=

x²+0*x-33=0

2. y³+9y2+5=0

it is qubic because it degree is3

3. 8m²+3m-6=0

it is quadratic because it highest degree is 2

4. 5a+9a²-0=0

it is quadratic it's degree is 2

hope this helps you

Answer 2

Step-by-step explanation:

1) Here, x is the only variable in the equation.

Maximum Index is 2 but there is no power of 1 i.e.

x²+5=33 is not quadratic equation.

2) Here, y is the only variable in the equation.

Maximum Index is 3 not 2. i.e. y³+9y²+5=0 is not

quadratic equation.

3) Here, m is the only variable in equation.

Maximum Index is 2. i.e. it is a quadratic equation.

4) Here, a is the only variable in equation.

Maximum Index is 2. i.e. it is a quadratic equation.

solution : 5a+9a²-0=0

9a²+5a-0=0.
