Question

identifique os coeficientes e calcule o discriminante para cada equação2 x elevado a 2 - 11x + 5 x = 0 ​

Answer 1

resposta:

a = 2

b = -6

c = 0

discriminante = 36

passo-a-passo;

$\boxed{\begin{array}{lr} 2x^2-11x+5x=0 \end{array}}\\\\\boxed{\begin{array}{lr} 2x^2-6x=0\\ax^2-bx=0 \end{array}}\\\\a=2\\b=-6\\c=0\\\\\boxed{\begin{array}{lr} \Delta=b^2-4.a.c\\\Delta=(-6)^2-4.2.0\\\Delta=36 \end{array}}$

Indique os coeficientes;

a = 2

b = -6

c = 0

calcule o valor do  discriminante;

36
