Question

escreva a equaçao ax2+bx+c=0 para: a) a= -1;b=0 e c=7 b) a=1;b= -5 e c = -6 c) a=2 ;b=0 e c= -25

Answer 1

ax² + bx + c = 0

a)

a = - 1; b = 0; c = 7

= - x² + 0x + 7 = 0

= - x² + 7 = 0

b)

a = 1; b = - 5; c = - 6

x² - 5x - 6 = 0

¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨
c)

a = 2; b = 0; c = - 25

2x² + 0x - 25 = 0

2x² - 25 = 0
