factor y^2-9x^2

Solution

factor

y^{2} - 9 x^{2}

Solution

(y + 3 x) (y - 3 x)

Solution steps

y^{2} - 9 x^{2}

Simplify

9 x^{2} : (3 x)^{2}

= y^{2} - (3 x)^{2}

Apply Difference of Two Squares Formula:

x^{2} - y^{2} = (x + y) (x - y)

y^{2} - (3 x)^{2} = (y + 3 x) (y - 3 x)

= (y + 3 x) (y - 3 x)

Popular Examples

∣ 5 y - 5 ∣ = ∣ 4 y + 6 ∣

\frac{x}{5} + 4 > - 3

(x + 8) (x + 15) = 0

x^2+(x+1)^2+(x+2)^2+(x+3)^2=54

x^{2} + (x + 1)^{2} + (x + 2)^{2} + (x + 3)^{2} = 54

simplify (8x^7x)/(12x^5yz^{-2)}simplify

\frac{8 x ^{7} x}{12 x ^{5} y z ^{- 2}}
