PLEASE ANSWER THIS, IT IS A TIMED TEST, AND I WILL GIVE BRAINLIEST. Find all real zeros: h(a) = 4a ^ 4 - 4a ^ 3 - 81a ^ 2 + a + 20

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.
