simplify

(x + 37) (x - 7)

x^{2} + 27 x - 21

Solution steps

(x + 37) (x - 7)

Apply FOIL method

(x + 37) (x - 7) : x^{2} + 27 x - 21

= x^{2} + 27 x - 21

\frac{1}{( 1 - i 3 ) ^{4}}

\frac{s}{( s + 1 ) ^{2}}

(x^{2} + 6 y^{2}) d x - 4 x y d y

(x^{2} - x + \frac{1}{6})^{2}

(\frac{x ^{2}}{2} + \frac{4}{x})^{6}
