[tex]8 {x}^{2} - 10x + 15 = 0[/tex]
we have: delta = b² - 4ac = (-10)² - 4.8.10 = - 380 < 0
So: no solution.
Ok done. Thank to me :>
Answer:
2
Step-by-step explanation:
8x^2 - 10x + 15 = 0 = formula -b +/- sqrt b^2 -4 * a * c / 2a = (- -10 ) = input +10+ (sqrt 10^2 -4 *( 8 * 15) ) /( 2* 8) = 10 +sqrt (96 * 120) / 16 = 10+ sqrt 11520 /16 = 16.7082039 and 10- (sqrt 10^2 -4 *( 8 * 15) ) /( 2* 8) = 10 -sqrt (96 * 120) / 16 = 3.29179607
