Question 1154247: Show work please
10. Work backwards to write a quadratic equation that will have solutions of x = 3 and x = -7.
11. Work backwards to write a quadratic equation that will have solutions of x = 12 and x = 2.
12. Work backwards to write a quadratic equation that will have solutions of x = -1/2 and x = 4. (Your equation must only have integer coefficients, meaning no fractions or decimals.)
13. Write a quadratic equation that will have a solution of only x = 0. Note: this means there will be a double solution of x = 0.
14. Write a quadratic equation that cannot be factored.
15. The product of two consecutive positive integers is 72. Find the integers.
16. The product of two consecutive negative integers is 10506. Write a quadratic equation that you could solve to find the integers.
17. Write a quadratic equation to find two consecutive odd natural numbers whose product is 63. Then find the numbers.
18. A tennis ball is launched straight upward with an initial velocity of 24.5 m/s from the edge of a cliff that is 117.6 meters above the ground. Which quadratic equation could be used to correctly determine when the ball will hit the ground:
19. Solve the equation you chose in question 18 to determine when the ball will hit the ground. (HINT: If you don't get one of the answers listed for this question, then maybe you chose the wrong equation in #18. Use this opportunity to double check your work!)
t = 8 seconds
t = 4 seconds
t = 3 seconds
t = -3 seconds
The ball will never reach the ground.
20. Using the same equation, determine when the ball is at a height of 49 meters. Answer by josgarithmetic(39617) (Show Source):
Picking just one of them:
----------------------------------------------------------------
The product of two consecutive negative integers is 10506. Write a quadratic equation that you could solve to find the integers.
-----------------------------------------------------------------
Integers n and n+1, if both are negative then product is positive. The lesser is n and the greater is n+1.
You can try factorization if you want to, or go ahead solving the quadratic equation. , and maybe try using solution to quadratic equation.
