因式分解 4-108x^2+121

解答

因式分解

4 - 108 x^{2} + 121

- (63 x + 55) (63 x - 55)

求解步骤

4 - 108 x^{2} + 121

对同类项分组

= - 108 x^{2} + 4 + 121

数字相加:

4 + 121 = 125

= - 108 x^{2} + 125

因式分解出通项

- 1

= - (108 x^{2} - 125)

分解

108 x^{2} - 125 : (108 x + 125) (108 x - 125)

= - (108 x + 125) (108 x - 125)

整理后得

= - (63 x + 55) (63 x - 55)

f a c t or 6 x^{10} m - 150 x^{2} m

f (x) = (sin (3 x))^{l n (x)}

f a c t or 9 x 8 + 6 x 4 (y + 2) + (y + 2) 2

f a c t or 4 (a^{2} - a p) + p^{2}

f a c t or sin (90 + 180 k)
