factor 16r^2-1.34r^2

Solution

factor

16 r^{2} - 1.34 r^{2}

Solution

14.66 r^{2}

Solution steps

16 r^{2} - 1.34 r^{2}

Rewrite

16 r^{2}

as

(2^{2} r)^{2}

= (2^{2} r)^{2} - 1.34 r^{2}

Rewrite

(2^{2} r)^{2} - 1.34 r^{2}

as

(2^{2} r)^{2} - (1.34 r)^{2}

= (2^{2} r)^{2} - (1.34 r)^{2}

Apply Difference of Two Squares Formula:

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

(2^{2} r)^{2} - (1.34 r)^{2} = (2^{2} r + 1.34 r) (2^{2} r - 1.34 r)

= (2^{2} r + 1.34 r) (2^{2} r - 1.34 r)

Refine

= (4 r + 1.34 r) (4 r - 1.34 r)

Factor

4 r + 1.34 r : r (1.34 + 4)

= (4 + 1.34) r (4 r - 1.34 r)

Factor

4 r - 1.34 r : - r (1.34 - 4)

= - r (1.34 + 4) r (1.34 - 4)

Refine

= - (1.34 + 4) (1.34 - 4) r^{2}

1.34 = 1.15758 \dots

= - (4 + 1.15758 \dots) (1.15758 \dots - 4) r^{2}

Refine

= 14.66 r^{2}
