x² = 24
x² = 24
Jack is thinking of two positive numbers, one of them is 4 more than the other and the sum of their squares is 208 what are the numbers?
Solve this equation using the quadratic formula.
3x² + 5x - 3 = 0
How would you solve this with the quadratic formula and leave the answer in
simplest radical form?
y² + 6y - 1 = 0
What are the solutions of the equation, 1.5x² - 4.5x = -3
Solve the following equations:
(i) 3 - 4x² = -85
(ii) -5x² = -500
Use the discriminant to determine how many real-number solutions the equation has.
1 - 7a² = -7a - 2
Since the quadratic formula when used to solve quadratic equations always spits out the correct answer, why do we not use only this method rather than even bothering with the other methods?
How do I solve this by factoring?
x^2 - x - 6 = 0
