Question

1. Find the zeroes of the following quadratic polynomials and verify the relationship between
the zeroes and the coefficients.
.
.
i.) 4u2+8u
.
.
ii.) t2-15​

Answer 1

Answer:

$(1).4u {}^{2} + 8u \\ 4u(u + 2) \: u = 0...u = - 2 \\ (2).t {}^{2} - 15 \\ t = + - \sqrt {15} \\ t = \sqrt{15 \: \: \: \:} \: \: t = - \sqrt{15}$
