Question

fatore
a) 64m²-48m+9
b) 4x²-20x+25
c) 121t²+22t+1

Answer 1

$a) \\ \\ 64 m^2 - 48m + 9 \\ \\ (8m - 3) *(8m - 3) \\ \\ => (8m - 3)^2$

=================

$b) \\ 4x^2 - 20x + 25 \\ \\ (2x - 5)*(2x - 5) \\ \\ => (2x - 5)^2$

=================

$c) \\ 12t^2 + 22t + 1 \\ \\ (11 + 1)* (11 + 1) \\ \\ => (11 + 1)^2$
