cab someone help me? solve by quadratic formula
3x^2 - 5x = -1
I cannot come up with the -5x and get the 1 for factoring.
put it into standard form:
3x^2 -5x +1=0
a= 3 b= -5 c=1
x= (5 +- sqrt (25 -12)/6
Yes, I can help you solve the quadratic equation using the quadratic formula.
To solve the equation 3x^2 - 5x = -1, you first need to rearrange it into the standard form, which is in the form ax^2 + bx + c = 0. In this case, the rearranged equation will be 3x^2 - 5x + 1 = 0.
Now, you can identify the values of a, b, and c, which are used in the quadratic formula. In this case, a = 3, b = -5, and c = 1.
The quadratic formula is x = (-b ± √(b^2 - 4ac)) / (2a).
Plugging in the values, we get x = (-(-5) ± √((-5)^2 - 4 * 3 * 1))/(2*3).
Simplifying further, we have x = (5 ± √(25 - 12)) / 6.
The discriminant inside the square root is 25 - 12, which is equal to 13. So, we have x = (5 ± √13) / 6.
Thus, the solutions to the quadratic equation 3x^2 - 5x = -1 using the quadratic formula are x = (5 + √13) / 6 and x = (5 - √13) / 6.
