Simplify (x2 + 3x)(x2 - x +4)
Answers
Answer:
x⁴ +2x³ + x² + 12x
Step-by-step explanation:
(x² + 3x)(x² - x +4)
= x²(x²) - x(x²) + 4(x²) + x²(3x) - x(3x) + 4(3x)
= x^4 - x³ + 4x² + 3x³-3x²+12x
= x⁴ +2x³ + x² + 12x

Algebra tiles to prove that 4 + 8x and 4(2x+1)
Answers
not sure what algebra tiles are
not sure how to absolutely prove I can prove it works at least most of the time by subsitute ing number for x
remember that 0,1,2 have special properties and are not very good for subsituting so try 4 4+8(4)=4(2(4)+1) true or false? 4+8(4)=4(2(4)+1) multipily 4+32=4(8+1) 36=4(9) 36=36 this is treu at least for the number 4 another way is to believe in the distributive property where a(b+c)=ab+ac so then 4(2x+1)=4(2x)+4(1)=8x+4=4+8x
4 + 8x
Now, see if the simplified form of 4(2x + 1) is equal to that.
4*2x = 8x 4*1 = 4
4 + 8x = 4 + 8x Correct
