Question

a² + 4a + 4
help me out please​

Answer 1

Find the zeroes of the polynomial

$a {}^{2} + 4a + 4$

Splitting the middle terms,

${a}^{2} + 2a + 2a + 4$

We get,

a(a+ 2) + 2(a+2)

ZEROES OF THE POLYNOMIAL ARE:-

a = -2 ans a = -2

Hence this equation follows b^2 - 4ac = 0 where the roots are real and equal.
