Question

I need help with this math problem please

Answer 1

option D

Explanation:

`9x^2 + 6x - 17 = 0 , \ where \ a = 9 \ , \ b = 6 \ , c = - 17`

`x = ( - b \ \pm √(b^2 - 4ac))/(2a) \\\\x = (-6 \pm √(36 - (4 * 9 * -17)))/(2 * 9)\\\\x = (-6 \pm √( 36 + 612))/(18)\\\\x = (-6 \pm √( 648))/(18)\\\\x = (-6 \pm √( 2^3 * 3^4))/(18)\\\\x = (-6 \pm √(2 * 2^2 * 3^ 4 ))/(18)\\\\x = (-6 \pm ( 2 * 9 )√( 2))/(18)\\\\x = (-6 \pm 18√(2))/(18)\\\\x = (-1 \pm 3 √( 2))/(3)`

Answer 2

It’s D

have a great day!
