Factor by grouping 2x^2-3x-35

What is the first step of an indirect proof of a number that is divisible by two

Which is a true statement comparing the graphs of x^2/6^2-y^2/8^2 = 1 and x^2/8^2-y^2/6^2 the foci of both graphs are the same points. the lengths of both transverse axes are the same. the directrices of = 1 are horizontal while the directrices of = 1 are vertical. the vertices of = 1 are on the y-axis while the vertices of = 1 are on the x-axis.

Solve each quadratic equation by factoring and using the zero product property. 14x - 49 = x^2
