Find the zeros of the polynomial 4x2-9 graphically
Answer :
Let
y = 4x2 - 9
Step 1 - Form a table for different values of x As:
Step 2- draw these points on x - y plane As :
So,
x = ( Ans )
Let
y = 4x2 - 9
Step 1 - Form a table for different values of x As:
y = 4x2 - 9 | |
x | y |
0 | -9 |
1 | -5 |
1.5 | 0 |
-1 | -5 |
-1.5 | 0 |
Step 2- draw these points on x - y plane As :
So,
x = ( Ans )
