Answer:
17x² - 12x + 0 = 0
Step-by-step explanation:
We can move all the terms to the same side of the equation first:
17x²=12x
17x² - 12x = 0
We know that a standard quadratic equation is in the form ax² + bx + c = 0, so we can substitute our values into this equation to match its form.
a=17
b=12
c=0
17x² - 12x + 0 = 0
First you can apply the a²-b² = (a+b)(a-b) theorem, you'll get:
(p²)² - 9² = (p²+9)(p²-9), but that's not all, you can apply it again on the last factor:
(p²+9)(p²-3²) = (p²+9)(p+3)(p-3)
The first factor cannot be simplified like that, so that's the furthest factorization. So answer (3) is the right one.
Answer:
Step-by-step explanation:
the sum of angles in a triangle is 180 degrees
18 + 72 + X = 180
90 + X = 180
X = 180 -90
X = 90
From largest to smallest:
3 hundreds (300) , 6 tens (60) , 8 ones (8)
hope this helped :)
