Question

check whether the following are quadratic equations are not x minus 4 Into X + 1 = 2 x minus 1 into X + 5​

Answer 1

(x - 4)(x + 1) = (2x - 1)(x + 5)

x² - 3x - 4 = 2x² - x + 10x - 5

x² - 3x - 4 = 2x² + 9x - 5

2x² - x² + 9x + 3x - 5 + 4 = 0

x² + 12x - 1 = 0

since the equation is of the form ax² + bx + c = 0 where a ≠ 0,

this is hence a quadratic equation

Answer 2

Hey buddy write it clearly...
