Answer:
1.
4x²+20xy+25y²
(2x+5y)(2x+5y) or (2x+5y)²
2.
A=2x²+7x+6
L=2x+3
w= x+2
lets check
A=L×w
2x²+7x+6=(2x+3)(x+2)
2x²+7x+6=2x²+3x+4x+6
2x²+7x+6=2x²+7x+6
they are equal therefore, the width is x+2
pa brainliest po salamat
ito ginawa ko kung bakit ko nakuha ang width
A=L×w
2x²+7x+6=(2x+3) ×W
divide both by 2x+3 para w nalang matira sa isang side
2x²+7x+6/2x+3=2x+3/ 2x+3(W )
2x²+7x+6/2x+3=W. factor mo yung numerator
(2x+3)(x+2)/2x+3 = W then cancel mo yung 2x+3
w=x+2
ganun lang po ka simple
