(x + 7)^{2}

x^{2} + 27 x + 7

Solution steps

(x + 7)^{2}

Apply Perfect Square Formula:

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

(x + 7)^{2} = x^{2} + 2 x 7 + (7)^{2}

= x^{2} + 2 x 7 + (7)^{2}

2 x 7 = 27 x

(7)^{2} = 7

= x^{2} + 27 x + 7

(y) (3 x + 7 y = 62)

(1, - 3) y (6, - 5)

(r - t)^{2}

(x + y) d x + x ln (x)

\frac{x ^{2} - 4 x + 2}{( x + 1 ) ( x - 1 )}
