factor 28+a^2-119

factor

28 + a^{2} - 119

(a + 91) (a - 91)

Solution steps

28 + a^{2} - 119

Subtract the numbers:

28 - 119 = - 91

= a^{2} - 91

Apply radical rule:

a = (a)^{2}

91 = (91)^{2}

= a^{2} - (91)^{2}

Apply Difference of Two Squares Formula:

x^{2} - y^{2} = (x + y) (x - y)

a^{2} - (91)^{2} = (a + 91) (a - 91)

= (a + 91) (a - 91)

a x + a y - a z + b x + b y - b z - c x - cy + cz

\frac{- x}{x}

x^{4} - (2 cos (x))

6 s^{2} + 5 s^{2} - 4

4 m^{2} - 4 m^{2}
