factor 4y^2-81

Solution

factor

4 y^{2} - 81

Solution

(2 y + 9) (2 y - 9)

Solution steps

4 y^{2} - 81

Apply exponent rules

= (2 y)^{2} - 9^{2}

Apply Difference of Two Squares Formula:

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

(2 y)^{2} - 9^{2} = (2 y + 9) (2 y - 9)

= (2 y + 9) (2 y - 9)

\frac{1}{2} (- 6)^{2}

8 π = 2 π r (r + 3)

simplify (12k^2-54k)/(6k)*6/(81-18k)simplify

\frac{12 k ^{2} - 54 k}{6 k} \cdot \frac{6}{81 - 18 k}

a^{2} + 3 a - 18 = 0
