Question

(3x+4) (4x+3) =6(2x-5) (x+2) is quadratic or not ?​

Answer 1

Answer:

(x + 1)2 = 2 (x – 3) x2 + 2x + 1 = 2x – 6. ⇒ x2 + 2x + 1 – 2x + 6 = 0. ⇒ x2 + 70. Since x2 + 7 is a quadratic ... 1 – x2 + 4x – 4 =0. ⇒ 7x – 3 = 0. Since 7x – 3 is a linear polynomial. ∴ x2 + 3x + 1 = (x – 2)2 is not a quadratic ...
