Answer:
⇢ [tex]{\boxed{\bold{Simplified \: form = 4x + -3y + 52}}}[/tex]
Step-by-step explanation:
⇢ [tex]\rm{7^{2} + 4x - 3y+3}[/tex]
ㅤ
From the above equation, expanding we get:-
⇢ [tex]\rm{49 + 4x + -3y+3}[/tex]
ㅤ
Now combining the like terms:-
⇢ [tex]\rm{49 + 4x + -3y + 3}[/tex]
ㅤ
⇢ [tex]\rm{(4x) + (-3y) + (49 + 3)}[/tex]
ㅤ
ㅤ
Point to remember:-
⇢ In the part of equation expansion, there we have to expand the given equation like: (7² = 7 * 7 = 49). Therefore we get that number.
