Answer:
b=9 and b=-21
Step-by-step explanation:
first step: move 195 to the other side by adding to get:
b^2+12b=189
now to find the constant you take the b value which is 12 divide that by 2 and square it. then add the product to both sides. 12/2=6, 6^2=36
b^2+12b+36=189+36
next factor b^2+12b+36.
(b+6)^2=225
square root both sides to get:
b+6=15 and b+6=-15
solve by subracting 6 to both sides and you get the 2 final answers.
b=9 and b=-21
Message me! i can prob help you (:
2x⁴(2x² + 3x + 4)
Simplify.
4x⁶ + 6x⁵ + 8x⁴ ==> The second answer choice.
We know this because :
Multiply 2x⁴ with 2x²
2x⁴ × 2x² = 4x⁶
Then, do :
2x⁴ × 3x = 6x⁵
Then, finally, do :
2x⁴ × 4 = 8x⁴
So, our answer looks like this :
4x⁶ + 6x⁵ + 8x⁴
~Hope I helped!~
I’m not positive, but I think it’s A
Simplest form of 15/42
15/42
=5/14 ( Divisible with 3 )
So, the simplest form is 5/14
