因式分解 144h^2+49i^2

解答

因式分解

144 h^{2} + 49 i^{2}

(12 h + 7) (12 h - 7)

求解步骤

144 h^{2} + 49 i^{2}

49 i^{2} = - 49

= 144 h^{2} - 49

化简

= (12 h + 7) (12 h - 7)

f a c t or e^{3 I n (x)}

f a c t or \frac{19}{( e ^{7} ) - 5} + 4

f a c t or sin (x - k x)

f (x) = 2 x (cos (x))^{2}

f a c t or (x + 5) (x^{2} - x - 2 - 5)
