You would find out that as you increased t, h would get smaller.

How do I Factor 42p⁴+9p³q²-18p²q²​
umka2103 [35]

Answer:

42p^4 + 9p^3q^2 -18p^2q^2 = p^2 (42p^2 + 9pq^2 - 18q^2)

Step-by-step explanation:

To answer this, we simply look for that term that is common to all

Looking at the given expression, we can see that the term we are looking for is p^2

Thus, we have that;

42p^4 + 9p^3q^2 -18p^2q^2 = p^2 (42p^2 + 9pq^2 - 18q^2)

When we multiply the term outside the bracket with each of the terms inside, we get back the original term

fenix001 [56]

Answer:

4x^{3}+8x^{2} +4x+3

Step-by-step explanation:

Hello

To simplify the polynomial we must eliminate the parentheses

by definition

ax^{n}*bx^{m} =abx^{n+m}

(2x-1)(2x^{2} +5x+3)+(3x+6)\\(4x^{3} +10x^{2} +6x-2x^{2} -5x-3)+(3x+6)\\\\We\ add\ the\ similar\ terms\\\\(4x^{3}+8x^{2} +x-3)+(3x+6)\\\\4x^{3}+8x^{2} +4x+3

I hope it helps

Have a great day
