Question

please help me guys it's urgent​

Answer 1

Step-by-step explanation:

Side = 2x -7

Area of square = side^2

= (2x-7)^2

= 4x^2 +49 -28x

Expand:

${(3 {k}^{2} - 2k )}^{2} \\ 9 {k}^{4} - 12 {k}^{3} + 4 {k}^{2}$

9k^4 -12k^3 + 4k^2

Answer 2

Step-by-step explanation:

Side = 2x -7

Area of square = side^2

= (2x-7)^2

= 4x^2 +49 -28x

Expand:

\begin{lgathered}{(3 {k}^{2} - 2k )}^{2} \\ 9 {k}^{4} - 12 {k}^{3} + 4 {k}^{2}\end{lgathered}(3k2−2k)29k4−12k3+4k2

9k^4 -12k^3 + 4k^2
