因式分解 (3p+7)+7p^2

解答

因式分解 completely

(3 p + 7) + 7 p^{2}

7 p^{2} + 3 p + 7

求解步骤

(3 p + 7) + 7 p^{2}

去除括号:

(a) = a

= 3 p + 7 + 7 p^{2}

改写为标准形式

= 7 p^{2} + 3 p + 7

f (t) = 20.3 (t)^{3} + 10

f a c t or 1 + 3 sin (x) - 4 sin^{3} (x)

f a c t or 5 x^{2} + 17 - 12

f a c t or 125 x^{6} - 27 y^{3} z^{9}

f a c t or x \cdot e^{3 t} + y \cdot e^{t}
