Given a quadratic equation of the form y = ax2 + bx + c, x is the independent variable and y is the dependent variable. Choose some values for x and then determine the corresponding y -values. Then plot the points and sketch the graph.

WebbSolving by factoring. Suppose we want to solve the equation x^2-3x-10=0 x2 −3x −10 = 0, then all we have to do is factor x^2-3x-10 x2 −3x −10 and solve like before! x^2-3x-10 x2 −3x −10 can be factored as (x+2) (x-5) (x +2)(x −5). [Show me the factorization.] The complete solution of the equation would go as follows: WebbThe first step is to substitute 2 in place of the variable y, which yields the arithmetic expression 4 − 2 (4 × 2) + 5 × 2. Using the order of operations, 4 − 2 (4 × 2) + 5 × 2 = 4 − 2 × 8 + 10 = 4 − 16 + 10 = −2. A machine that works at a constant rate processes 18 pounds of fruit every 3 hours.
