Question

ILL GIVE BRAINLIEST AND 10 POINTS

Answer 1

Answer:

$(7m^2+10)^2$

Step-by-step explanation:

This is a quadratic in disguise. To visualize this better, let $x=m^2$. We have:

$49x^2+140x+100$

To factor, we can write out the format $(ax+y)(bx+z)$. We're looking for numbers $a$, $b$, $y$, and $z$ such that the following is true:

• $a\cdot b=49$
• $a\cdot z+b\cdot y=140$  
• $y\cdot z=100$

We find the following numbers:

$a=7,\\y=10, \\b=7, \\z=10$

Thus, we have:

$(7x+10)(7x+10)$

Substitute back $x=m^2$ to get your final answer:

$(7m^2+10)(7m^2+10)=\boxed{(7m^2+10)^2}$
