If you mean: 2x squared = 50 Divide both sides by 2: x squared = 25 Square root both sides: x = 5
If you mean: (2x-7y)(x+y) then it is 2x squared -5xy -7y squared
x^2+x^2=2x^2
No.
No.
2x2 ÷ x = 2x
Divide by 'x'; x2+xy/x = x(x+y)
Oh, dude, you're hitting me with some math now? Okay, so x squared times 2x squared is like multiplying the coefficients and adding the exponents, so it's 2 times 1 times x to the power of 2 plus 2, which simplifies to 2x to the power of 4. Easy peasy lemon squeezy!
3x squared - x squared = 2x squared
If you mean: 2x squared = 50 Divide both sides by 2: x squared = 25 Square root both sides: x = 5
No. x squared is x times x, whereas 2x is x + x.
If you mean: (2x-7y)(x+y) then it is 2x squared -5xy -7y squared
x2 - 2x = x(x-2)
Add the x's squared together to get 2x^2+x. You cannot add anymore so the answer is 2x^2+x
It is: -2x squared
2x2 + 2x = 2x(x+1)
2 squared X 3 squared = 5 squared
