Question

Which of the following is not a linear equation? (a) x2 + 4x = x(x+5)+ 8 (b) x(x-5) = -3x (x-8) (o) 3 (x+7) = 2x + 8 (d) x(x+3) = -x(3-x) +5​

Answer 1

$option \: (b)$

Step-by-step explanation:

$(b) \: \: x(x - 5) = - 3x(x - 8) \\ {x}^{2} - 5x = - 3 {x}^{2} + 24x \\ 4 {x}^{2} - 29x = 0\\ It \: \:is \:\:a \:\:quadratic \:\:polynomial.$

Answer 2

Answer:

c)3(x+7)=2x+7 this answer is not linear equation
