Solve this quadratic equation using the quadratic formula 5-10x-3x^2=0

Step-by-step explanation:

the quadratic equation is x= -b plus or minus the square root of b^2-4ac and all of that over 2a. to solve using the quadratic formula, move the terms into the a^2+2ab+b^2 format, which in this case would be -3x^2-10x+5 here you take each number and plug it into the equation

10 plus or minus square root of 100-4(-3)(5) over 2(-3)

which is 10 plus or minus the square root of 160

over -6

since i did most of the math here, i think you can solve for the roots now. just do 10- square root of 160 all divided by -6 and 10+ square root of 160 all divided by -6
