Which of the following equations represents the polynomial function with zeros 5, negative start fraction one over two end fraction, and −3, and a y-intercept of 15?

A. y = 2(x-5)(x+1/2)(x+3)
B. y = -(x+5)(2x-1)(x-3)
C. y = (x+5)(2x-1)(x-3)
D. y = -(x-5)(2x+1)(x+3)

Factorize: x^2+8x+10 i just solved it but i don't know if the process is correct

Sam claims that cos x =sin y if x and y are congruent angels. is sam correct ?
