This produces a quadratic in y in which the first-degree term is missing. Use Vièta's method to solve the quadratic equations: %3D %3D - x² + 8x = 9. x² + 10x = 144. (b) x² +12x = 64. (c) 3x² + 10x = 32. [Hint: Multiply both sides by 3 (d) and let z = 3.x.] barieh (a) %3D %3D %3D %3D 7). 13. To solve the equation x² + ax = b² geometrically, René Descartes would have used the method as Mndi described. Draw a line segment AB of length b and at A erect a perpendicular AC of length a/2. With C as center, construct a circle of radius a /2 and draw a line through B and C , intersecting the circle at points D and E. Prove that the length of the segment BE is the value of x that satisfies x² +ax = b². %D until

Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
