factor 0.21x^2+2.84-42.58

factor

0.21 x^{2} + 2.84 - 42.58

(0.45825 \dots x + 6.30396 \dots) (0.45825 \dots x - 6.30396 \dots)

Solution steps

0.21 x^{2} + 2.84 - 42.58

Add/Subtract the numbers:

2.84 - 42.58 = - 39.74

= 0.21 x^{2} - 39.74

Rewrite

0.21 x^{2} - 39.74

(0.21 x)^{2} - (39.74)^{2}

= (0.21 x)^{2} - (39.74)^{2}

Apply Difference of Two Squares Formula:

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

(0.21 x)^{2} - (39.74)^{2} = (0.21 x + 39.74) (0.21 x - 39.74)

= (0.21 x + 39.74) (0.21 x - 39.74)

0.21 = 0.45825 \dots

= (0.45825 \dots x + 39.74) (0.21 x - 39.74)

39.74 = 6.30396 \dots

= (0.45825 \dots x + 6.30396 \dots) (0.21 x - 39.74)

0.21 = 0.45825 \dots

= (0.45825 \dots x + 6.30396 \dots) (0.45825 \dots x - 39.74)

39.74 = 6.30396 \dots

= (0.45825 \dots x + 6.30396 \dots) (0.45825 \dots x - 6.30396 \dots)

y^{(n)}
