Question

2x-1=x^2
-x^2+2x-1 --> (solve it with Quadratic quation to find x




7x-6=x^2
-x^2+7x-6 -> (solve with quadratic equation

Answer 1

this is the quadratic equation: \[x = -b \pm \frac{\sqrt{b ^{2}-4ac}}{2a}\]

Answer 2

\[-b \pm \sqrt{b ^{2}-4ac}/2a\] this is the equation for 1. a=-1; b=2; c=1.. plug in & solve

Answer 3

same goes for #2

Answer 4

THANK YOU

Answer 5

no problem!!

Answer 6

@math456 where did u get c=1 from? shouldn't it be c=-1?
