factor (5x+y)^2-16x^2+8x-1

factor

(5 x + y)^{2} - 16 x^{2} + 8 x - 1

9 x^{2} + 10 x y + 8 x + y^{2} - 1

Solution steps

(5 x + y)^{2} - 16 x^{2} + 8 x - 1

(5 x + y)^{2} : 25 x^{2} + 10 x y + y^{2}

= 25 x^{2} + 10 x y + y^{2} - 16 x^{2} + 8 x - 1

Simplify

25 x^{2} + 10 x y + y^{2} - 16 x^{2} + 8 x - 1 : 9 x^{2} + 10 x y + 8 x + y^{2} - 1

= 9 x^{2} + 10 x y + 8 x + y^{2} - 1

dd x (cos (2 x + 3))

x^{2} + (3 x - 5)

\frac{x ^{2} - 6}{- 2}

2 (7^{2} - 4 \cdot 7 + 9)
