($t^{4}$+8)($t^{4}$-3)
You are given ($t^{4}$$)^{2}+5t^{4}-24.Factor out: (t^{4}$$)^{2}$+8$t^{4}$-$3t^{6}$-24 -break out the middle number by finding what numbers add up to 5 and multiply to give -24.The numbers are -3 and 8- (($t^{4}$$)^{2}$+8$t^{4}$)+($-3t^{4}$-24) -find the GCD of the first two and last two terms- $t^{4}$($t^{4}$+8)-3($t^{4}$+8) -take ($t^{4}$+8) and factor it out- The factored expression is ($t^{4}$+8)($t^{4}$-3)
