Solve for all zeros, reduce as much as possible, show all work. x^4 + 14x^2 + 45 = 0

First, factor it: (x²+5)(x²+9)=0
x²=-5=5i², or x²=-9=9i²
x=(√5)i, -(√5)i, 3i, or -3i

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
