Question

Factorise fully 50-2y²​

Answer 1

2y² - 50 = 2(y² - 25) = 2(y² - 5²) = 2(y + 5)(y - 5) Hope it helps you! izvoru47 and 10 more ... the perimeter of a rectangle is 17cm and its width is 3 \6 find its length full souletion​.

Answer 2

`\textsf{Hey there!}`

`\textsf{Switch the equation: }`
`\mathsf{-2y^2+ 50}`

`\mathsf{-2y^2+2*5^2}`

`\mathsf{2(- (2y^2)/(2)+ (2*5^2)/(2))}`

`\mathsf{2(- y^2)+5^2)}`

`\mathsf{5^2= 5*5 = 25}`

`\mathsf{2(-y^2+25)}\\\mathsf{2(-y^2+5^2)}\\\mathsf{Flip: 2(5^2-y^2)}\\\mathsf{2((5-y))((y+5))}\\\boxed{\boxed{\mathsf{Thus, your\ answer\ is: \boxed{\bf{2(-y+5)(y+5)}}}}}\checkmark`
