NEED HELP FAST PLEASE. Write an equation in which the quadratic expression 4x^2-14x+42 equals 0
And show all work please, and don't ignore it if it shows its answered, it's prolly just some lowlife looking for points

answer:

7/4 + 10.91i /4   ,   7/4 - 10.91i/4.

Step-by-step explanation:

4x^2-14x+42 = 0

2(2x^2 - 7x + 21) = 0

We need to numbers whose product is  42 and whose sum is -7.  

They don't exist so we can solve it using the formula for a quadratic equation:

x = [ - (-7) +/- sqrt (49 - 4*2*21)] / 4

= 7/4 +/-  sqrt (-119) / 4

= 7/4 + 10.91i /4   ,   7/4 - 10.91i/4.

answer: 59

step-by-step explanation:

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
