expand [2e-11f]^2

expand

[2 e - 11 f]^{2}

121 f^{2} - 44 e f + 4 e^{2}

Solution steps

(2 e - 11 f)^{2}

Apply Perfect Square Formula:

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

a = 2 e, b = 11 f

= (2 e)^{2} - 2 \cdot 2 e 11 f + (11 f)^{2}

Simplify

(2 e)^{2} - 2 \cdot 2 e 11 f + (11 f)^{2} : 4 e^{2} - 44 e f + 121 f^{2}

= 4 e^{2} - 44 e f + 121 f^{2}

Rewrite in standard form

= 121 f^{2} - 44 e f + 4 e^{2}

L (1, 4) M (4, 0) N (2, 0) P (- 1, - 2)

(e^{x} + 5)^{2}

(x^{2} - 2.86 x) (x - 3, 62)

20 + 90 sin (3 (t - 2))

1 (- 3 x + 2 y = 6)
