Verify whether the values of x given in each case are the zeroes of the polynomial or not ?
If the value of x =

INFORMATION :-

the zeroes of a polynomial also called its roots are the values of x for which the corresponding value of y {f(x)} is zero.

while seeing zeroes in a graph they are the points where the graph intersects the x- axis.

SOLUTION :-

Now, we're given a function such that

f(x) = 3x²- 1

put f(x) = 0 and solve for x to get the zeroes of this function.

f(x) = 3x² - 1 = 0

3x² - 1 = 0

3x² = 1

x² =

x = ±

so the roots of f(x) = 3x²- 1 are :-

Comparing the values given to us and the values we found out.

while the

step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
