Question

• State whether the following statements are true or false :
1. The degree of the polynomial p (x) = 3 + 5x + x
+ x2 is 3.
2. The formula to find the discriminant of a quadratic equation is D = b^-4ac.
3. 3, 3, 3, ... is an AP.
4. cos 45º =​

Answer 1

Answer:

1. False

2. False

3. False

4. √(2)/2

Step-by-step explanation:

1. General formula of 3rd degree equation: x^3+ax^2+bx+c=0.

2. Discriminant = b^2-4ac.

3. General formula of an AP = (a-d),a,(a+d),(a+2d),(a+3d),...........,(a+nd).

4. Cos45° = √(2)/2.
