1.What is the solution to x2 + 3x + 25 = 0? use quadratic formula

2.What are the zeroes of y = x2 + 14x +40

3.What is the solution to the following equation?x2 + 7x – 18 = 0


Respuesta :

1 : complex # : [ - 3 ± i√91 ] / 2 

2 y = [ x + 7 ]² - 9 ---> x = 3 ± 7

3 x^2 - 7x - 18 = 0
x^2 - 9x + 2x - 18 = 0
x(x - 9) + 2(x - 9) = 0
(x - 9)(x + 2) = 0
x = -2
x = 9


I hope that helps I honestly suck at algebra anymore
