What’s c? Not valid question
Answer: pretty sure the answer is A
Step-by-step explanation:
1/2(2) + 4 = 1 + 4 = 5
2 + 6 - 1/2(2) -2 = 8 - 1 - 2 = 5
Answer: When the quadratic equation can be factored or solved by completing the square, you do not need to use the quadratic formula
Step-by-step explanation: In the form ax² + bx + c
Whenever <em><u>a</u></em> is 1 (implied, no coefficient of x²) and the constant, <u><em>c</em></u>, is a multiple of numbers whose sum or difference is equal to <u><em>b</em></u>, factoring is much quicker and easier than using the quadratic formula.
Even when there is a coefficient of x², there are procedures to find the factors and solve for x without resorting to the quadratic formula.
