x^2 +2x -3 =0 solve by completing the square and then by quadratic formula
Find the zeros of each function by using the quadratic formula. F(x) = x2(squared) +10x+9 g(x) = 2x2(squared) +4x -12 h(x)= 3x2(squared)-3x+3/4 f(x)= x2(squared)+2x-3 g(x)=2x2(squared)+3x+1 g(x)=...

Solve 3/x + 3/2x = 2 Please explain how to answer this question. Thank you :)
x2+x-12=0 x2+3x-5=0 x2+4x+7=0
select the approximate values of x that are solutions to f(x)=0 where f(x)=4x^2 +7x+6
x2-x-20=0
x2+4x+7=0 And x2+3x-5=0
x2+4x+6=0
