Answer:
Fred is 6
Jimmy is 17
Step-by-step explanation:
Jimmy's age =2x +5
Fred's age =x
x+2x+5=23
3x=23-5
3x=18
x=6
Jimmy's age =2(6)+5=17
Fred is 6
First rewrite in the form ax² + bx + c = 0
So a=2, b=0 (there are no x terms!) and c = 10-4=6.
x = +-√-(4*2*6) / 2*2 = +- √-48 / 4 = +-√(-3*16) / 4 = +-i√3
The solutions are imaginary. Are you sure there is no typo in the equation?
