What two numbers multiple together to equal -50 and add together to equal to 2?
xy=-50 x+y=2, so y=2-x Substitute y=2-x to xy=-50 x(2-x)=-50 2x-x2=-50 -x2+2x+50=0 x2-2x-50=0 cannot be factorised. So use the abc formula ax2+bx+c=0 a=1, b=-2, c=-50, pm=plus minus, v=square root x=[-b pm v(b2-4ac)]/2a x=[2 pm v(4-4.1.-50)]/2.1 x=[2 pm v(204)]/2 x= [2 pm 2v(51)]/2 x=1 pm v(51) so the answer is 1+v51 and 1-v51 or in decimal (approx): 8.1414 and -6.1414
