Question

Which expression is equivalent to 10x2y + 25x2? 5x2(2y + 5) 5x2y(5 + 20y) 10xy(x + 15y) 10x2(y + 25)

Answer 1

we have

$10x^{2}y+ 25x^{2}$

we know that

$10=2*5\\25=5*5$

substitute

$(2*5)x^{2}y+ (5*5)x^{2}$

Factor $5x^{2}$

$(5x^{2})(2y+ 5)$

therefore

the answer is

$(5x^{2})(2y+ 5)$

Answer 2

The answer would be A. 5x2(2y+5)
