Question

Fill in the missing steps for the derivation of the

Answer 1

Answer:

step 1: $ax^2$+bx+c=0

step 2:$ax^2+bx=-c$

step 3: $x^2+\frac{b}{a}x=\frac{-c}{a}$

step 4:$x^2+(\frac{b}{2a})^{2} =\frac{b}{2a}) ^{2} \frac{-c}{a}$

step 5: $(x+\frac{b}{2a} )^{2} =\frac{b^2-4ac}{4a^2}$

step 6:$x=\sqrt{\frac{b^2-4ac}{4a^2} }$

step 7: $x=\sqrt{\frac{b^2-4ac}{2a}$

Step-by-step explanation:

from step 6 there should be a plus and minus sign before the square root.
