H= -16t^2+16t+192 When will the ball hit the ground?

-16t^2+16t+192= 0 (when the ball hits the ground, h will be zero)

Use the quadratic formula to solve the equation (If you don't know how to solve quadratic equations, just ping me dude and I'll try my best to help you)

We get x=-3 and 4

Now since time can't be negative, therefore the answer is after 4 seconds

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5

step-by-step explanation:

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
