Question

a² + a + 1/4
I need answer step by step​

Answer 1

Answer:

${a}^{2} + a + \frac{1}{4} = 0 \\ \frac{4 {a}^{2} +4 a + {1} }{4} = 0 \\ 4 {a}^{2} + 4a + 1 = 0 \\ 4 {a}^{2} + 2a + 2a + 1 = 0 \\ 2a(2a + 1) + 1(2a + 1) = 0 \\ (2a + 1)(2a + 1) = 0 \\ {(2a + 1)}^{2} = 0 \\ 2a + 1 = 0 \\ 2a = - 1 \\ a = \frac{ - 1}{2}$
