Question

Write the zeroes of the polynomial x²+2x+1
explain step by step

Answer 1

${x}^{2} + 2x + 1 = 0 \\ {x}^{2} + x + x + 1 = 0 \\ x(x + 1) + 1(x + 1) \\ (x + 1)(x + 1) = 0 \\ so \: to \: make \: it \: zero \: x + 1 \: should \: be \: xero \: so \: - 1 \: is \: the \: root$

Answer 2

Solution:-☺

${x}^{2} + 2x + 1 \\ {x }^{2} + x + x + 1 \\ x(x + 1) + 1(x + 1) \\ (x + 1)(x + 1) \\ zeroes = - 1 > - 1$
