Verified answer

step 1: factor the num using 2x-6

step 2: simplify

.

Divide 8x2 - 14x - 30 by 2x - 6

Divide 2(4x2 - 7x - 15) by 2(x - 3)

Divide 2(x - 3)(4x + 5) by 2(x - 3)

Answer is (4x + 5)

Here si the answer...

8x2-14x(-30)/2x(-6)

=16-420/(-12)

=-404/-12

=33.67

therefore the answer is 33.67.

BTW the answer became a positive because when divided two minus makes a positive answer. =) Hope i helped! =)

(8x^2 - 14x - 30)/(2x - 6)

= 2(4x^2 - 7x - 15)/2(x - 3)

= 2(4x^2 + 5x - 12x - 15)/2(x - 3)

= 2[(4x^2 + 5x) - (12x + 15)]/2(x - 3)

= 2[x(4x + 5) - 3(4x + 5)]/2(x - 3)

= 2(4x + 5)(x - 3)/2(x - 3)

= 2(4x + 5)/2

= 4x + 5

(8x^2 - 14x - 30) / (2x - 6)

(4x + 5)(2x - 6) / (2x - 6)

4x + 5

(2x - 6) (4x + 5) / (2x - 6)

Just cancel the common numbers:

= 4x + 5

= (8x² - 14x - 30)/(2x - 6)

= (2[4x² - 7x - 15])/(2[x - 3])

= (4x² - 7x - 15)/(x - 3)

= ([4x + 5][x - 3])/(x - 3)

= 4x + 5

Answer: 4x + 5

16-420/-12=-404/-12

answer...=33.67
