Answer:
6
Step-by-step explanation:
i guess the answer is 6
the value of x is 6
If x = -1 this gives -1 + 3 - 3 + 1 = 0
so x = -1 is one root
if we divide the expression by (x + 1) we get the quotient x^2+2x+1
which factors to (x+1)(x+1)
so the multiplicity is 3
Step-by-step explanation:
sin 75°: Now using the formula for the sine of the sum of 2 angles, sin(A + B) = sin A cos B + cos A sin B, we can find the sine of (45° + 30°) to give sine of 75 degrees.
