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

$\textsf{Hey there!}$

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

$\mathsf{-2y^2+2\times5^2}$

$\mathsf{2(- \dfrac{2y^2}{2}+ \dfrac{2\times5^2}{2})}$

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

$\mathsf{5^2= 5\times5 = 25}$

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