Jaishan notices that if he squares two numbers and finds the difference of his answers he gets the same result as multiplying the sum and the difference of the two numbers.For example, if he chooses 9 and 3: \[9^{2}\] — \[3^{2}\] = 81 — 9 = 72 and (9 + 3) x (9 — 3) = 12 x 6 = 72 Show that this works with the numbers 6 and 2²6²-2²=32,(6+2)x(6-4)=326²+2²=32,(6+2)x(6-2)=326²-2²=32,(6+3)x(6-3)=324²+2²=32,(4+2)x(4-2)=323²+2²=32,(3+2)x(3-2)=32 (b) Jaishan uses this to find \[83^{2}\] — \[17^{2}\] WITHOUT using long multiplication. How did he do it and what is the answer?(83+17)x(83-17)=6600(83+17)x(83+17)=6600(83-17)x(83-17)=6600(83+17)+(83+17)=6600(83+17)-(83+17)=6600 37.
