Ineed need to find the intercept form and the zero product property to solve and the x intercepts

The square root of 9x plus 7 plus the square rot of 2x equall to 7

If rt is greater than ba, which statement must be true ?

The diagram represents the polynomial 4x2 + 23x – 72. what is the factored form of 4x2 + 23x – 72? (4x + 8)(x – 9) (4x – 8)(x + 9) (4x + 9)(x – 8) (4x – 9)(x + 8)
