Solve for x. Chapter 5 Practice
- x^2 – 12x + 11 = 0 2) x^2 + 6x + 8 = 0 3) 6x^2 – 48 = -12x
- 3x^2 = -4 + 8x 5) 8x^2 + 16x = 42 6) x^2 +14x – 38 = 0
- x^2 -12x = -23 8) x^2 -10x + 26 = 8 9) -3x^2 + 12x – 16
10) 30-4(x-11) =-70^2 11) -3(x + 7)(x – 11)=0 10) 2x(3x-5)(x+2)=
Write each problem in vertex form.1) y = x (^2) – 2x + 5 2) y = x (^2) + 16x + 71 3) y= -x (^2) – 14x +
- y = 2x^2 + 36x + 170 5) y = -6x^2 – 12x – 13 6) y =4x^2 – 20x + 1

Write a possible quadratic equation for the parabolas given below in factored form.
Write the quadratic equation for the parabolas given below in vertex form.
Word Problem: h(t) = -16t (^2) + v 0 t + h 0 Aerospace engineers use quadratic functions to model the motion of a rocket. They^ wherev^ h(t)^0 is the vertical velocity, h^ is the height(feet) of the object,^0 is the starting height.^ t^ is the time(sec), determined that they will launch a rocket from the ground at an initial vertical velocity of80 feet per second.a) Write this equation in standard form.
b) Find the time(s) it will take for the rocket to reach 64 feet above the ground. c) What is the maximum height the rocket with reach? d) How long will it take for the rocket to reach its maximum height? e) When will the rocket hit the ground?
