Add 1/4 to both sides of the equation : On the right hand side we have : 1 + 1/4 or, (1/1)+ (1/4) We would like to show you a description here but the site won’t allow us.The solution (s) to a quadratic equation can be calculated using the Quadratic Formula: The "±" means we need to do a plus AND a minus, so there are normally TWO solutions ! The blue part ( b2 - 4ac) is called the "discriminant", because it can "discriminate" between the possible types of answer: when it is negative we get complex solutions.The equation (x – √2) 2 – √2(x+1)=0 has two distinct and real roots. Simplifying the above equation, x 2 – 2√2x + 2 – √2x – √2 = 0. x 2 – √2(2+1)x + (2 – √2) = 0. x 2 – 3√2x + (2 – √2) = 0. D = b 2 – 4ac = (– 3√2) 2 – 4(1)(2 – √2) = 18 – 8 + 4√2 > 0. Hence, the roots are real and distinct.. Plant all wizard101, how to shadow box tiktok game
