Solution for 42x^2-49x=0 equation:



42x^2-49x=0
a = 42; b = -49; c = 0;
Δ = b2-4ac
Δ = -492-4·42·0
Δ = 2401
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{2401}=49$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-49)-49}{2*42}=\frac{0}{84} =0 $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-49)+49}{2*42}=\frac{98}{84} =1+1/6 $
