WebbE.g. (x + 5)(x − 1) = x 2 + 5x − x − 5 = x 2 + 4x − 5 Remember: expressions with three terms like x 2 + 4x − 5 are known as trinomials. An expression that contains more than two terms and includes variables and coefficients is called a polynomial. WebbStep 1: Use quadratic formula with a=1, b=-2, c=-3. x= −b±√b2−4ac. 2a. x= −(−2)±√(−2)2−4(1)(−3) 2(1) x= 2±√16. 2. x=3 or x=−1.

WebbLearn how to solve differential equations problems step by step online. Solve the differential equation dy/dx=x^2y^3. Group the terms of the differential equation. Move the terms of the y variable to the left side, and the terms of the x variable to the right side of the equality. Simplify the expression \\frac{1}{y^3}dy. Any expression multiplied by 1 is … WebbImagine this: There's an equation x = 2. Right now, x is only equal to two. Square both sides, and x^2 = 4. For some reason, if you want to take the square root of both sides, and you get x= +/- 2, because -2 squared is still equal to four. But, according to the original equation, x is only equal to 2. raa.rjet.com
