Question

Find the value of 4x² - 12x + 9. Also verify the relationship between the zeros and the coefficients.​

Answer 1

Answer:

$4x ^{2} - 12x + 9 \\ \\ 4x ^{2} - 4x - 9x + 9 \\ \\ 4x(x - 1) - 9(x - 1) \\ (x - 1)(4x - 9) \\ \\ x = 1 \: \: x = \frac{9}{4} \\ \\ <em><u>relation \: between \: co - efficent \: \\ \\ sum \: of \: zeroes \: = \frac{ - coefficient \: of \: x \: }{</u></em>coefficient \: of \: x ^{2} } \\ \\ sum \: of \: zeroes \: = \frac{ - 12}{4}$
