Question

By using the completing the square method pls with the full procedure by solving it​

Answer 1

Answer:

$1.10 {x}^{2} - 13x - 3 = 0 \\ product \: = 10 \times - 3 \\ = - 30 \\ sum \: = 13 \\ factors \: = ( - 15 \: \: 2) \\ 10 {x}^{2} - 15x + 2x - 3 = 0 \\ 5x(2x - 3) + 1(2x - 3) = 0 \\ (5x + 1)(2x - 3) = 0 \\ either \: 5x + 1 = 0 \\ 5x = - 1 \\ x = - \frac{1}{5} \\ or \: 2x - 3 = 0 \\ 2x = 3 \\ x = \frac{3}{2} \\ x = 1.5 \\ 2. {x}^{2} - 2x + 1 = 0 \\ product \: = 1 \\ sum \: = - 2 \\ factors \: ( - 1 \: - 1) \\ {x}^{2} - x - x + 1 = 0 \\ x(x - 1) - 1(x - 1) = 0 \\ (x - 1)(x - 1) = 0$
