if x = 4 and y = 3 then find the value of
x^2 + 2xy
__________
x^2 + 4y^2
Thank you so much!! :))
just plug in the values....
let me know what you get
4^2 + 2(4)(3)
_____________
4^2 + 4(3)^2
16 + 24
________
16 + 36
40
= ___
52
= 10
___
13
am i right ??
To find the value of the given expression, let's substitute the given values of x and y into the expression and solve step by step.
Given:
x = 4
y = 3
First, substitute the values of x and y into the expression:
x^2 + 2xy
__________
x^2 + 4y^2
= (4^2) + 2(4)(3)
______________
(4^2) + 4(3^2)
= 16 + 8(3)
__________
16 + 4(9)
= 16 + 24
__________
16 + 36
= 40
______
52
Therefore, the value of the given expression is 40/52, which can be further simplified as 10/13.
So, the final solution is 10/13.
I hope this explanation was helpful!
