Given the polynomial 21x^4+3y-6x^2+34 What polynomial must be subtracted from it to obtain 29x^2-7? What polynomial must be added to it to obtain a first degree polynomial?

Astudent draws two parabolas on graph paper. both parabolas cross the x-axis at (-4, 0) and (6,0). the y-intercept of thefirst parabola is (0, –12). the y-intercept of the second parabola is (0-24). what is the positive difference between the avalues for the two functions that describe the parabolas? write your answer as a decimal rounded to the nearest tenth.

Ming says that 0.24 > 1/4 because 0.24= 2/4. which best explains mings error
