factor 9r^2-16

Solution

factor

9 r^{2} - 16

Solution

(3 r + 4) (3 r - 4)

Solution steps

9 r^{2} - 16

Apply exponent rules

= (3 r)^{2} - 4^{2}

Apply Difference of Two Squares Formula:

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

(3 r)^{2} - 4^{2} = (3 r + 4) (3 r - 4)

= (3 r + 4) (3 r - 4)

Popular Examples

r^{2} - 10 r + 34 = 0

3(y-5)-7(y-2)=3

3 (y - 5) - 7 (y - 2) = 3

2 (2) - 5

simplify (8x)/(21y^3)*(7y^2)/(16x^3)simplify

\frac{8 x}{21 y ^{3}} \cdot \frac{7 y ^{2}}{16 x ^{3}}

simplify pi*1/4 simplify

π \cdot \frac{1}{4}
