expand (x^2-4x+3)(x^2+4x+3)

expand

(x^{2} - 4 x + 3) (x^{2} + 4 x + 3)

x^{4} - 10 x^{2} + 9

Solution steps

(x^{2} - 4 x + 3) (x^{2} + 4 x + 3)

Distribute parentheses

= x^{2} x^{2} + x^{2} \cdot 4 x + x^{2} \cdot 3 - 4 x x^{2} - 4 x \cdot 4 x - 4 x \cdot 3 + 3 x^{2} + 3 \cdot 4 x + 3 \cdot 3

Simplify

x^{2} x^{2} + x^{2} \cdot 4 x + x^{2} \cdot 3 - 4 x x^{2} - 4 x \cdot 4 x - 4 x \cdot 3 + 3 x^{2} + 3 \cdot 4 x + 3 \cdot 3 : x^{4} - 10 x^{2} + 9

= x^{4} - 10 x^{2} + 9

3 i (- 5 + i)

\frac{x ^{2} - 4}{x ^{2} - 4 x + 4}

4 x^{3} y^{2} + 18 x y^{3} - 30 x^{2} y

(- x^{2} - 4 x - 5) + (- x^{2} + 8 x + 8)

(4 x^{2} - 8 x - 2) (x^{4} + 3 x^{2} + 4 x)
