SIMULTANOUES EQUATIONS WITH 1 QUADRATIC

x= -0.90, y= 2.30

x= 1.40, y= 9.20

Step-by-step explanation:

y= 3x+5

y= 4x²+x

4x² + x= 3x + 54x² - 2x - 5 = 0x= (-b±√b²-4ac)/2aa=2, b= -2, c= -5x= (2±√4+4*4*5)/8= (2±√84)/8x= (2-√84)/8= (1-√ 21 )/4= -0.90 x= (2+√84)/8= (1+√ 21 )/4= 1.40x = -0.90  ⇒ y= -0.90*3+5= 2.30x = 1.40 ⇒ y= 1.40*3+5= 9.20

The operation is suck a c@ck? !
