What is the first step in writing f(x) = 3x2 + 6x – 8 in vertex form?
a) factor out 3 from each term.
b) form a perfect square trinomial by keeping the value of the function equivalent.
c) write the trinomial as a binomial squared.
d) factor out 3 from the first two terms.

How many zeros does the function f(x)=4x3-x2+1 have

Solve each quadratic equation by factoring and using the zero product property. x^2 + 18x = 9x

White shapes and black shapes are used in a game. some of the shapes are circles. while the rest are squares. the ratio of the number of white shapes to the number of black shapes is 5: 11. the ratio of the number of white cicrles to the number of white squares is 3: 7. the ratio of the number of black circles to the number of black squres is 3: 8. work out what fraction of all the shapes are circles.
