Question

factorise 4^2+9^2+16^2+12−24−16

Answer 1

$\longrightarrow{\blue{}}$ ${4}^{2} + {9}^{2} + {16}^{2} + 12 - 24 - 16$

$\longrightarrow{\blue{}}$ $(4 \times 4) + (9 \times 9) + (16 \times 16) + 12 - 24 - 16$

$\longrightarrow{\blue{}}$ $16 + 81 + 256 + 12 - 40$

$\longrightarrow{\blue{}}$ $365 - 40$

$\longrightarrow{\blue{}}$ $325$
