Q: Factor by grouping

2x^2 + x - 28

First, Choose a form with appropriate signs.

Then, fill in the blanks with numbers to be used for grouping

Finally, show the factorization

Find the value of the cosine for angle a

If 2(a^2+b^2)=(a+b)^2 then, > a+b=0, > ab=0, > a=b, > 2a=b

M the table below represents a linear function f(x) and the equation represents a function g(x): x f(x)−1 −50 −11 3g(x)g(x) = 2x − 7part a: write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points)part b: which function has a greater y-intercept? justify your answer. (4 points)
