Question

if the ordered pairs (x^2-3x,y^2+4y)and (-2,5) are equal then find x and y​

Answer 1

Answer:

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

Step-by-step explanation:

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
