Question

write the discriminant of the quadratic equation (x+5)²=2(5x-3)​

Answer 1

Answer:

${x}^{2} + 25 + 10x = 10x - 6$

${x +}^{2} + 25 + 6 + 10x - 10x$

${x}^{2} + 31 + 0 = 0$

$a = 1 \\ b = 31 \\c = 0$

$d = {b}^{2} - 4ac$

$d = {31 }^{2} - 4 \times 1 \times 0$

$d = {31}^{2} - 0$

$d = 961$
