Question

find the zero of the quadratic polynomial 5 x square minus 4 minus 8 x and verify the relationship between the zeros and coefficient of the polynomial​

Answer 1

Answer:

$5x { }^{2} - 8x - 4 \\ 5x {}^{2} - 10x + 2 x - 4 \\ 5x(x - 2)2(x - 2) \\ (5x - 2)(x - 2) \\ x = \frac{2}{5 \: \: } \: \: \: \: x = 2 \: zeroes \: of \: the \: plono...$

now put the value of x in equation first you get the value
