(4x+5)(4x-5) is equal to 16x^2+20x-20x-25
The positive and negative 20x cancel out
Leaving you with: 16x^2 - 25
[S/N this is a pattern that shows up a decent amount. Whenever you have something that looks like (x^2-y^2) it factors out to (x+y)(x-y). It might be helpful to remember]
The next one, (4x+5)2, just follows the distributive property. Multiply both components within the parentheses bye the coefficient of 2: 8x+10
Answer:
+3x + 7 to make the sum x3
Step-by-step explanation:
to find the sum of 3 and to solve it to get the value of x
.2= 2/10
now you have to reduce it and it is 1/5
