factor 10a^4-a^3-21a^2

factor

10 a^{4} - a^{3} - 21 a^{2}

a^{2} (5 a + 7) (2 a - 3)

Solution steps

10 a^{4} - a^{3} - 21 a^{2}

Factor out common term

a^{2} : a^{2} (10 a^{2} - a - 21)

= a^{2} (10 a^{2} - a - 21)

Factor

10 a^{2} - a - 21 : (5 a + 7) (2 a - 3)

= a^{2} (5 a + 7) (2 a - 3)

(x - 2)^{3} - x (x - 5) \cdot (x - 1) = 2 - 3 x

(1 + i)^{8}

n^{3} + 5 n^{2} - 9 n - 45

1 + 6 x + 9 = 2 (3 x + 3) - x

4 t^{2} + 11 t + 2 = 0
