ANSWER :-
65
Given -
To find -
Solution -
→ 1 - 4(2)[(-1)(2) + 3(2)(-1)]
→ 1 - 8 [(-2) + (-6)]
→ 1 - 8 (-8)
→ 1 + 64
→ 65 Ans
Procedure -
• This question is from the Algebraic identites.
• In this question we are given with an Algerbraic expression and with the values of x,y and z.
• In this question we will put 2 in place of x , -1 in place of y and 2 in place of z and then we will equate the whole value.
• First we will solve the values given inside the braket, which will be RHS and we wil multiply 4 with 2 which will be 8 and will write it as 1 - 8 which will be called as LHS.
• We will keep the LHS part the same after getting a final answer in RHS in the last we will add 1 + 64 will be give the value 65.
• Remember that :-
