Explanation:
"express the equation in "color(blue)"standard form"express the equation in standard form
rArrx^2+x-6=0larrcolor(blue)"in standard form"⇒x2+x−6=0←in standard form
"the factors of - 6 which sum to + 1 are + 3 and - 2"the factors of - 6 which sum to + 1 are + 3 and - 2
rArr(x+3)(x-2)=0⇒(x+3)(x−2)=0
"equate each factor to zero and solve for x"equate each factor to zero and solve for x
x+3=0rArrx=-3x+3=0⇒x=−3
x-2=0rArrx=2x−2=0⇒x=2
