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.
250×.40 = 100.00
250.00+100.00 =350.00
your answer is $350.00
You have the following equation:
11h - (2h -1) = 118
In order to solve for h the previous equation you proceed as follow:
11h - (2h -1) = 118
elminate parenthesis by takin into accoun the multilpication of signs
11h - 2h + 1 = 118 simplify similar terms and subtract 1 both sides
9h = 117 divide by 9 both sides
h = 117/9
h = 13
Hence, the solution to the given equation is h = 13
