Answer 1

Answer:

Mark brainlist

Step-by-step explanation:

1)If the ordered pairs (x2-3x, y2+4y)&(-2,5) are equal, then find X&y.

x2-3x+2=0

By splitting the middle term factorization we get,

x2-x-2x+2=0

x (x-1)-2(x-1)

(x-2)(x-1)=0

X=2 or x=1

y2+4y-5=0

y2– y +5y-5=0

y(y-1) +5(y-1)=0

(y-1) (y+5)= 0

Y=1 or y=-5

x = 1 or x = 2 and y = 1 or y = -5

Answer 2

Answer:

(x2 – 3x, y2 + 4y) = (-2, 5) x2 – 3x = -2 x2 – 3x + 2 = 0 (x – 2) (x – 1) = 0 x – 2 = 0 or x – 1 = 0 x = 2 or 1 y2 + 4y = 5 y2 + 4y – 5 = 0 (y + 5) (y – 1) = 0 y + 5 = 0 or y – 1 = 0 y = -5 or y = 1 The value of x = 2, 1 and 7 = -5, 1 Read more on Sarthaks.com - https://www.sarthaks.com/934091/if-the-ordered-pairs-x-2-3x-y-2-4y-and-2-5-are-equal-then-find-x-and-y
