x=-1/2 or x=-0.5 simplified.

Answer 2

Thanks!

Answer 3

highest degree of number tell you how many solution (total) qudratic equation should have
for example x^3+4x + 3
this equation should have 3 roots

Answer 4

roots=zeroes = solution

Answer 5

for more info
A polynomial of degree n will have n roots, some of which may be multiple roots (they repeat). For example, is a polynomial of degree 3 (highest power) and as such will have 3 roots. http://www.regentsprep.org/regents/math/algtrig/ate13/highpolylesson.htm
