Answer 4

Do you want me to help you to solve these step by step?

Answer 5

yes please

Answer 6

I already got the first one

Answer 7

\[x ^{2}=14x-49\]
First step is to bring the terms on the right hand side to the left hand side. Can you do that, being careful with the signs?

@BMI229 Are you there?

Answer 9

\[x ^{2}=14x-49\]
First subtract 14x from both sides
\[x ^{2}-14x=14x-14x-49\]
The terms in x on the right hand side cancel so we now have
\[x ^{2}-14x=-49\ ................(1)\]
and effectively we have moved 14x to the left hand side (with a change of sign).
Can you add 49 to both sides of equation (1) ?
