Answer 1

Answer:

here's the answer dear ...hope it helps

mark me as brainliest !!

Answer 2

Answer:

$(x - 2)(x + 1) = (x - 1)(x + 3) \\ {x}^{2} + x - 2x - 2 = {x}^{2} + 3x - x - 3 \\ {x}^{2} - {x}^{2} - x - 2x - 2 + 3 = 0 \\ - 3x + 1 = 0 \\-(3x - 1) = 0</p><p></p><p> it \: is \: \: a \: quadratic \: euation.$
