simplify (11-7i)^2

Solution

simplify

(11 - 7 i)^{2}

Solution

72 - 154 i

Solution steps

(11 - 7 i)^{2}

Apply Perfect Square Formula:

(a - b)^{2} = a^{2} - 2 ab + b^{2}

(11 - 7 i)^{2} = 1 1^{2} - 2 \cdot 11 \cdot 7 i + (7 i)^{2}

= 1 1^{2} - 2 \cdot 11 \cdot 7 i + (7 i)^{2}

Simplify

1 1^{2} - 2 \cdot 11 \cdot 7 i + (7 i)^{2} : - 154 i + 72

= - 154 i + 72

Rewrite in standard complex form:

72 - 154 i

= 72 - 154 i

18 x^{2} + 47 x + 5 = 0

3/4 x+9/2 >= 7/2+11/4

\frac{3}{4} x + \frac{9}{2} \geq \frac{7}{2} + \frac{11}{4}

- x - 1 = 4 x - 11

factor-20x^{10}-2x^5+4 factor

- 20 x^{10} - 2 x^{5} + 4

(x-7)/4+(25(x-2))/3 =(5x+35)/4+5/2 (x-7)

\frac{x - 7}{4} + \frac{25 ( x - 2 )}{3} = \frac{5 x + 35}{4} + \frac{5}{2} (x - 7)
