​

Answer 1

Step-by-step explanation:

some of them are solved

Answer 2

Answer:

Step-by-step explanation:

These solutions for Quadratic Equations are extremely popular among Class 10 students for Math Quadratic ... (1) x2 + 5x – 2 = 0 ... ⇒(x2-2x+1)=2x+3⇒x2-4x-2=0 ... So, it is of the form ax2 + bx + c = 0 where a = 6, b = 3 and c = 5. ... (8) 3x2-2√6x+2=0 ... Find m if (m – 12) x2 + 2(m –12) x + 2 = 0 has real and equal roots.
