factor 7u^2-28m^2

Solution

factor

7 u^{2} - 28 m^{2}

Solution

7 (u + 2 m) (u - 2 m)

Solution steps

7 u^{2} - 28 m^{2}

Factor out common term

7 : 7 (u^{2} - 4 m^{2})

= 7 (u^{2} - 4 m^{2})

Factor

u^{2} - 4 m^{2} : (u + 2 m) (u - 2 m)

= 7 (u + 2 m) (u - 2 m)

Popular Examples

|2x-5|-|4-x|=10

∣ 2 x - 5 ∣ - ∣ 4 - x ∣ = 10

2y+18y+37=(y+4)^2

2 y + 18 y + 37 = (y + 4)^{2}

x^{2} + 4 x + 14 = 0

(2-x)(x+1)(x^2-16)>0

(2 - x) (x + 1) (x^{2} - 16) > 0

simplify (-12x^{-2}y^4)/(3xy^{-3)}simplify

\frac{- 12 x ^{- 2} y ^{4}}{3 x y ^{- 3}}
