find all solutions to the equation 10x^2 - 7x - 6 = 0.
thank you!!
Use quadratic equation: a=10, b=-7, c=-6, have you not learned the quadratic formula? Search it up, this problem is extremely easy, giving the answer would be funny. this is systematically solved problem
In Quadratic Formula for this quadratic a = 10 b = -7 and c = -6
\(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\) becomes
\(x = {7 \pm \sqrt{7^2-4(10)(-6)} \over 2(10)}\) which will give you two values of x which are the 'roots' or ' zeroes' of the equation.....
The quad formula is fine.....I always like to see if I can factor, first, before resorting to the "Q"....
(5x - 6) ( 2x + 1) = 0
Setting each factor to 0 and solving for x produces
5x - 6 = 0 2x + 1 = 0
5x = 6 2x = -1
x = 6/5 x = -1/2
