@welshfella @FaiqRaees Hey guys, could you help if you can?

faiqraees · Answer

take any value of x and input it in the given equation. Now take those x and y values and plug in the given choices if 0=0 comes then the choice is right

@FaiqRaees But what if the values of x and y haven't been given?

faiqraees · Answer

take any value of x like x = 0 now input it in the equation
y^2+7y+1=0 Now work out the value of y. This will be our correct x and y values. Now input them in the given equations

@FaiqRaees How would I work out the value of y here? Is factorization necessary?

faiqraees · Answer

Yeah work out the value of y in any way
