Question

SOLVE USING ALGEBRAIC IDENTITIES
1.(-444+352)2
2.(987+567)(987-567)
3.(98757+98577)2

NOTE:in first and in last questions 2 is square​

Answer 1

Answer:

1.8464

Step-by-step explanation:

1.(-444+352)^2

[^=square ]

=(-444)^2+2×(-444)×352+(352)^2

[(a+b)^2=a^2+2ab+b^2]

=1,97,136-3,12,576+1,23,904

=8,464

2.(987+567)(987-567) [(a+b)(a-b)=a^2-b^2]

=(987)^2-(567)^2

=9,74,169-3,21,489

=6,52,680
