Answer 1

Answer:

$8. \: {t}^{2} - 19 + 50 = 0$

${t}^{2} + 31 \: = 0$

${t}^{2} = \: - 31$

$t \: = \sqrt{31i}$

here i stand for complex no if u haven't heard about complex no then recheck the question

$9. \: {y}^{2} - 8y + 16 = 0$

${y}^{2} - 4y - 4y + 16 = 0$

$y(y - 4) - 4(y - 4) = 0$

$(y - 4)(y - 4) = 0$

$y = 4$

$10. {x}^{2} = 0$

${x}^{2} = 0$

$x = 0$

$11. \: {x}^{2} + 0x + x = 0$

${x}^{2} = 0$

$x = 0$

hope its helps
