which are not in standard form ? make it in s.f and identify the values of a,b and c, (x+7) (x-7) = -3x

Sagot :

you need to multiply (x+7) and (x-7) To get the First solution
[tex] x^{2}-7x+7x-49=3x[/tex]
Then Transpose 3x to The left Side
It will be
[tex] x^{2} -7x+7x-3x-49=0 [/tex]
Then combine like terms
[tex] x^{2} -3x-49=0[/tex]
That is the final answer
Now The Value Of A, B, and C 
A=0
B=3
C=49

That's All Thanks You
