Since it's a right angle the sum of the two angles equals 90°
(8y-2)°+60°=90°
8y-2=90-60
8y-2=30
8y=30+2
8y=32
y=32/8
y=4
<span>3x</span>² <span>- 8x -3 = 3x</span>² - 9x + x - 3 =
= 3x² - 9x + x - 3 = 3x* ( x - 3) + 1* (x - 3) =
= 3x * (x - 3) + 1 * (x - 3) = (3x + 1) (x - 3)
Answer (3x + 1) (x - 3)
I think, you just find a number that could be divided by or divided for.
