Steve's expression is $2(2x+5)^{2}-7$

For x=3, the expression is equal to $235$

Part b)

Jasmine's expression is

$(3x^{2})+(25x)$

For x=2, the expression is equal to $62$

Step-by-step explanation:

Part a)

Let

n-----> the first term

The expression is

$(n-7)$

$n=2(2x+5)^{2}$

$2(2(3)+5)^{2}-7=242-7=235$

Part b)

Let

n-----> the first term

Jasmine's expression is

$(3x^{2})+(25x)$
